Phase 3b+3c: ui props use ':'; drop dead needs/uses synonyms (Rule A)

Browse source 
3b: widget props go from key=value to key: value (parse_widget). emit_ui and
ludic-fmt unchanged (AST-identical; ':' formats correctly by default). Chose the
colonized form over parenthesized named-args — minimal churn, no new grammar.
Migration: tools/ludic-tools/migrate_ui.c. menu golden byte-identical.

3c: removed the undocumented, unused 'needs'/'uses' clause synonyms from
parse_system; reads/writes stay.

Reseeded, fixpoint holds, test.sh 14/14, check-docs + check-vocabulary green.

evaluated at build time, so `font=reg(R_FONT)` reads a value the game set first.
Each `id=Name` mints a `UI_Name` handle (the `ui` block name too), used from
