* Image sequences: a gap in the numbering holds the previous frame, as After Effects
Split out of #1876 (originally 7850cbf4), because it reverses the colour bars
documented in #297 and needs its own discussion.
After Effects 2026 shows the last existing file across a gap in a sequence's
numbering (files 1, 2, 4, 5 show frame 2 at frame 3; read back from After
Effects). EffectCraft drew colour bars there. The media pool now holds the
previous file (Footage::sequence_file_held); colour bars remain only where no
file precedes the frame. Missing-frame reports on import are unchanged.

* Image sequences: hold the first file of the preceding number across a gap; fix the import warning
A gap now holds the file sequence_file picks for the preceding number, so
files sharing a number do not switch at the gap. The Report Missing Frames
warning says the previous frame is held instead of "shown as placeholders".

* Image sequences: Interpret Footage says a gap holds the previous frame
The Interpret Footage note for a numbered sequence with gaps still said the
missing frames are shown as colour bars; the media pool holds the previous
frame there now. The note, its comment and two test doc comments say so,
and a forms test checks the note's wording.

file.import without the flag (scripts, agents, files opened from the command line,
the CLI's templates) turned `lockin_line1.png` into a one-frame image sequence.
ImportOptions.sequence defaults to false in After Effects, so picked and dropped files
now import as stills unless `sequence: true`; folders' numbered runs still import as
sequences, and the Import dialog's Sequence checkbox is unchanged.
