feat(modules): port loldle-quote

Phase 6b of the go-port-cloud-run plan. Same shape as loldle-emoji but
with quote-pool data and default 6 guesses (vs emoji's 5).

- internal/modules/loldlequote: champions.go (embed quotes.json),
  state.go (game/stats/config persistence), render.go (italic clue +
  guess list, HTML-escaped), handlers.go (handleQuote / handleGiveup /
  handleStats / handleSetMax), loldlequote.go (Module Factory).
- Reuses internal/modules/util/chathelper and internal/champname so
  the new module adds no helper duplication.
- 4 commands wired in cmd/server/main.go: loldle_quote (public),
  loldle_quote_giveup (public), loldle_quote_stats (public),
  loldle_quote_setmax (private).
- 17 tests: lookup (embed + redaction-marker check), render
  (escapes), state (round-trip + JS-wire-format decode + streak
  sequence), handlers (no-arg / win / unknown / duplicate / giveup /
  stats / setmax owner+nonowner).

go test -race -count=1 ./... clean across all 16 packages;
golangci-lint clean.
