Three fixes that prevented precon decks from loading into actual gameplay:
1. ui.js: window.startGame() now calls startGameWithDecks() when
setupDeckChoices has entries (the 3-tab selector stores choices there).
Previously it called initGame() which looked for old deck-sel-{i}
dropdowns that no longer exist.
2. engine.js: loadPreconForPlayer() now fetches .dck file content from
the backend (/api/lab/precons/deck?fileName=...) when precon.decklist
is empty. Falls back to fetching precon-decks/{file} directly.
PRECON_DATA entries only have metadata (name, commander, set) — the
actual card list lives in the .dck files.
3. engine.js: parseDeckList() now handles .dck bracket-style section
headers like [Commander], [Main], [metadata]. Previously only matched
bare text like 'COMMANDER:' without brackets. Also skips [metadata]
lines (e.g. 'Name=Elven Empire').
4. routes/precon.py: Added GET /api/lab/precons/deck?fileName=... endpoint
to serve raw .dck file content for the LAN client.
