* Sonar: explicit imports, fn paths for closures, extract helpers for cognitive complexity
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
* Fix imports
* Fix serde imports
* Fix engine imports
* Fix clippy gate and a type error from the explicit-import change
Remove the unused imports the review flagged (cf.rs, pivot.rs, tables.rs, cmd/sheet.rs) so clippy -D warnings passes, and point the backstage parent-folder lookup at Path::to_str, which the fn-path rewrite had broken.

* Apply rustfmt to the explicit-import cleanup so the fmt gate passes
* Share the per-directory font path expansion in theme.rs
The candidate font lists repeated the same loop over the Linux font
directories in every role. A single helper expands them in the same order,
so the lookup order is unchanged and the duplicated blocks go away.

* Read the Windows fonts folder in one place in theme.rs
Every script-font list repeated the same WINDIR lookup. A single helper
returns the same path, so the duplicated lines go away without changing
which font files are tried.

* Build the light and dark UI palettes from one table in theme.rs
Tokens::light() and Tokens::dark() listed the same 40 colour fields in the
same order, so every change had to be made twice. A single palette
constructor takes the mode and picks each colour's value, so each field is
written once and both modes keep their exact colours.

* Share the Noto CJK font list between the CJK script lists in theme.rs
The Japanese, Simplified and Korean lists each repeated the same loop over
the Linux CJK directories with a different locale file name. One helper
builds that loop, and each list keeps its own face index, so the lookup
order is unchanged.

* Share Linux Noto directory list across Thai and Hebrew font lookups
Removes the duplicated directory arrays flagged by SonarCloud new-code duplication.
* Reuse in_dirs for Thai and Hebrew Noto font candidates
Removes the remaining duplicated per-directory loops flagged by SonarCloud.
* Share one font-list builder for the Thai and Hebrew faces
The two per-script functions repeated the same Windows, macOS, Linux and
variable-font setup. A single script_fonts helper now builds both lists,
keeping the candidate order unchanged, which clears the Sonar duplication gate.

Sweep findings from the ac8da7d4 security scan (storytold-gridcraft-agent-
findings.json), remaining on main at 72c1d57d:
- finding 14 (crates/calc/src/eval.rs:988): every lambda invocation now
spends one charge against a per-cell work budget (16M — one per cell of
the largest array a reference may expand to), so a hostile, deeply
nested LAMBDA/LET formula stops at the bound a legitimately wide one
could reach instead of growing exponentially with nesting. Exhaustion
is #CALC!, like the existing depth cap. Metered at `call_lambda_values`
so every path into a body is counted (direct application, MAP/REDUCE/
SCAN/BYROW/BYCOL/MAKEARRAY, D-function criteria); the criteria
sub-evaluator hands its spend back to the parent.
- finding 16 (crates/functions/src/criteria.rs:313): `match_from` takes a
step budget (1<<26: an honest match against Excel's 32,767-char cell
ceiling costs a few hundred thousand steps), and `wildcard_find` drops
the leading star run (a no-op for a prefix match) so the first literal
anchor skips straight to its occurrences; all suffix attempts share one
budget. Star churn degrades to no-match instead of quadratic work.
Unit tests: mock-host exhaustion/under-budget for lambda applications
(eval::fuel_tests), nested REDUCE under budget in full recalc, wildcard
behaviour unchanged.

- PMT: take rate / m first so (pv + fv) / m can't overflow for a tiny rate (PMT(1e-300,10,1e12)).
- Keytips probe: an empty params object keys like no params.
- Number Stored as Text check reads the same accounting parentheses as typed entry.
- Lookups: a NaN number falls back to the general comparison instead of comparing equal.

Typed entry, VALUE and arithmetic now read $(1,234), $ (5) and (5)% as
negative numbers, as Excel 365 does. Parentheses no longer nest: (-5),
((5)), $5% and dates in parentheses stay text. This changes main's
((100)) from 100 to text; the no-recursion guard from #2180 is kept and
its test now asserts the new result.
PMT computed (1 + rate)^nper with powf, which rounds 1 + rate first and
drops the low bits of a small rate. Over 400 synthetic probes that left
PMT up to about 1000 ULPs from Excel (59 bit-exact); the ln_1p/exp_m1 form
is within 4 ULPs (244 bit-exact). A loan schedule guarded by
IF(p - SUM(principal) > 0, ...) turns on those bits: in 3000 synthetic
schedules main disagreed with Excel on the number of live periods in 1382,
the fix in 823.
Also follows Excel at the edges: a rate of -1 or less is #NUM!, a huge
nper gives -pv*rate instead of #NUM!, a tiny rate no longer collapses, and
a small negative rate keeps its payment. IPMT, PPMT, CUMIPMT and CUMPRINC
pick this up through pmt_calc. FV and PV are unchanged: Excel's own FV/PV
sit further from the exact value than the current powf form does.
The tests allow the one-ULP libm difference between platforms.
- #2369: its test joins the single ui-egui integration-test binary (tests/it), as main now builds them.
- #2367: a cell set to empty text is a blank entry and doesn't grow the AutoFilter (CodeRabbit).
- #2387: MOD's range check also covers the sign-corrected remainder (CodeRabbit).

From the local CodeRabbit review: the result was bounded per match, but
one match's expansion was built whole first, so a replacement repeating
$0 10,000 times over a 32,767-character match allocated about 330 MB
before the check. The replacement is now split into pieces as regex's
Captures::expand reads it (template_expands_like_regex checks they agree)
and appended piece by piece within the bound: 327 MB peak became 7 MB
(regexreplace_bounds_its_result).

- Text coercion: digits too many for a finite number are not a number,
and a fraction must come out finite, so "1 <400 digits>/<400 digits>"
(inf/inf) no longer coerces to NaN (test overlong_digits_stay_text).
- VLOOKUP/HLOOKUP and the D-functions' field index refuse NaN, which
passed their "< 1" checks and became index 0, then underflowed
(test nan_index_is_a_value_error; hostile_inputs_never_panic now also
passes NaN and infinity to every function).
- REGEXREPLACE replaces match by match and gives up once the result can
only be too long, instead of building every replacement first: the
32,767 x 32,767 worst case went from 1.05 GB peak to 7 MB
(test regexreplace_bounds_its_result).
#2165 (MAP's size check) is already fixed on main by the broadcast cap
(836b2698, #2182), whose test covers MAP.
Also adds my contributors/people.toml entry.

LINEST, LOGEST, TREND and GROWTH built k x k normal-equation matrices
(plus two copies in sym_inverse, O(k^3)) with k taken straight from the
known_xs shape, so one formula could allocate gigabytes and abort on open.
More than 255 predictors is now #VALUE!, and more than 1e9 rows x k^2
multiply-adds is #NUM!, both checked before any allocation.

Sheet names starting with '.' or reading as R1C1 (R, C, RC, R1C1...) were saved
unquoted, so Excel could not open the file; PivotTable sources and ADDRESS left
cell-like names (A1) bare. The quoting rule, unquoting and sheet splitting now
live once in gridcraft_core::addr and replace the copies in the formula printer,
pivot, ADDRESS, chart, xlsx, Solver, Go To and the Name Box (which now reads ''
as ').
