Evan 3de5fb4204 Move map metadata into info.json and generate map TypeScript from it (#4227)
**Add approved & assigned issue number here:**

N/A — maintainer refactor.

## Description:

Makes each map's `info.json` the single source of truth for map metadata
— adding a map is now a folder with `image.png` + `info.json`, a
`gen-maps` run, and an en.json display name.

**info.json / manifest.json carry full map metadata.** Every
`map-generator/assets/maps/<map>/info.json` declares `id` (the
`GameMapType` enum key), `name` (the enum value — wire format, unchanged
for all 94 maps), `translation_key`, `categories`, and
`multiplayer_frequency` (the public-playlist weight that used to be the
`FREQUENCY` record in MapPlaylist.ts). The generator validates
everything and mirrors it into `resources/maps/<map>/manifest.json`. 23
stale info.json `name` values were normalized to the canonical enum
value; enum values are byte-identical, so replays and stored game
configs are unaffected.

**The generator emits the TypeScript and discovers maps itself.** New
`map-generator/codegen.go` generates `src/core/game/Maps.gen.ts`
(`GameMapType`, `GameMapName`, `mapCategories`, `mapTranslationKeys`,
`multiplayerFrequency` — now a full `Record<GameMapName, number>`,
killing the old `Partial`) on every run; `Game.ts` re-exports it. The
hardcoded map registry in `main.go` is gone — maps are auto-discovered
from the `assets/maps` / `assets/test_maps` directories. MapConsistency
tests fail with a "run `npm run gen-maps`" message if info.json,
manifest.json, and Maps.gen.ts drift. The tracked
`map-generator/map-generator` binary is rebuilt to match.

**New categories: continents + world/cosmic/tournament/other,
multi-category support.** `continental`/`regional`/`fantasy`/`arcade`
are replaced by `featured`, `world`, `europe`, `asia`, `north_america`,
`africa`, `south_america`, `oceania`, `antarctica`, `cosmic`,
`tournament`, and `other`. Maps can list multiple categories, so
straddlers (Black Sea, Bosphorus, Caucasus, Between Two Seas, Bering
Sea/Strait, Mena, Strait of Gibraltar, Hawaii, Arctic) appear under both
regions. Featured is itself a category (same 7 maps as before).
MapPlaylist keeps its arcade exclusion via an explicit set.

**Map picker UI.** Two tabs: **Featured** (default — featured maps plus
a Favorites section when maps are starred) and **All** (one prominent
collapsible bar per category with a map count, collapsed by default).
The selected map is prepended to the featured grid when it lives
elsewhere. `getMapName()` resolves through the generated
`mapTranslationKeys`, which also fixes tourney maps never resolving a
valid translation key.

## Please complete the following:

- [ ] I have added screenshots for all UI updates (maintainer change —
picker described above)
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory

## Please put your Discord username so you can be contacted if a bug or
regression is found:
