M14: Telugu (తెలుగు) interface language (#349)

* M14: Telugu interface font

- The interface takes `Telu` faces from craft-fonts after the CJK and Arabic ones, on the web too
- Test: Telugu text has glyphs in every family and its conjuncts are shaped

* M14: Telugu interface language

- Complete te catalog: 1,984 entries plus whole-phrase Undo/Redo; te and te_IN locales use it
- Undo and Redo labels use a catalog phrase when the language has one (Telugu puts the verb last)
- Tests, docs, attribution, parity and ROADMAP

* M14: catalog contexts for labels with two meanings

- tl_ctx! gives the signature pad's Type, the Action Wizard's Start and the comment menu's Edit their own context; Telugu translates them, other languages keep their current translation
- Preferences' All tools goes through the catalog in every language
