feat(clan): add a past-24-hours overview card to the clan page

[ryanbarlow97]

Description:

The clan Overview tab showed only member count and open/invite status, so there was no signal of whether a clan is actually active right now. The public API already serves a windowed aggregate per clan (GET /public/clan/:tag?start=&end=, capped at one day server-side), which is exactly the rolling window we want.

This adds a Past 24 Hours card below the stat tiles on the clan Overview tab, showing the game count, a win/loss bar (reusing renderWLBarRow), and the weighted win score, loss score and ratio — formatted to match the clan leaderboard.

Behaviour details:

• The window sent is exactly now - 24h → now; the endpoint rejects anything longer.
• Like the clan leaderboard, the endpoint counts public Team games only (unranked, excluding HvN). The card's header tooltip states this so the numbers aren't misread as all-modes.
• The fetch runs in parallel with the clan detail request, so it adds no latency to the visible load, and is guarded by asyncGeneration + tag like the Discord lookup.
• It is deliberately not part of detailCache — a rolling window goes stale, so it refetches per mount.
• Any failure (non-2xx, schema mismatch, timeout, offline) hides the card rather than showing an error; the rest of the overview stands on its own.
• Zero-activity windows render "No games in the past 24 hours." instead of empty metrics.

No games in the window	Endpoint unavailable (card hidden)

Renders in both Overview layouts; metric labels wrap rather than truncate in the narrower left column of the Discord two-column layout:

Files

• src/core/ClanApiSchemas.ts — ClanWindowStatsSchema / ClanWindowStatsResponseSchema. The endpoint's teamTypeWL / teamCountWL breakdowns are intentionally not modelled (Zod strips them).
• src/client/ClanApi.ts — fetchClanRecentStats(tag), unauthenticated with a 5s timeout.
• src/client/components/clan/ClanDetailView.ts — the card, its loader and the skeleton/empty/hidden states.
• resources/lang/en.json — five new clan_modal.recent_24h_* keys; reuses the existing leaderboard_modal.win_score / loss_score / ratio labels and tooltips.
• tests/client/clan/ClanRecentStats.test.ts, tests/client/clan/ClanRecentStatsCard.test.ts, plus a mock in ClanModalTestUtils.

Verification

Full suite (3280 tests), tsc --noEmit, oxlint and eslint all clean. The four states above were rendered against the real dev client in headless Chromium.

Screenshots are linked by commit SHA (3807f7b) from a side branch that has since been deleted, so the commit is unreachable — the images above will 404 once it is garbage-collected. Reviewers: if they've gone, ask and they'll be re-attached.

Please complete the following:

• I have added screenshots for all UI updates
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory

Walkthrough

Added a validated rolling 24-hour clan statistics API flow. ClanDetailView loads statistics independently, rejects stale responses, and renders loading, empty, unavailable, win/loss, score, and ratio states with localization.

Changes

Clan recent statistics

Layer / File(s)	Summary
Statistics contract and fetch flow src/core/ClanApiSchemas.ts, src/client/ClanApi.ts, tests/client/clan/ClanRecentStats.test.ts	Added schemas and public types for bounded clan statistics. Added unauthenticated 24-hour fetching with uppercase tags, ISO timestamps, timeout handling, response validation, and failure results.
Statistics view and validation src/client/components/clan/ClanDetailView.ts, tests/client/clan/ClanModalTestUtils.ts, tests/client/clan/ClanRecentStatsCard.test.ts, resources/lang/en.json	Added concurrent loading, cache-restoration refreshes, stale-response guards, localized labels, and statistics-card rendering for loading, unavailable, empty, and metric states.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🔵 Low · up to bf192

The PR adds the past-24-hours clan activity card and its API parsing; the remaining merge-readiness concern is that validation currently lives in dependency-free core code, creating a bounded module and runtime-dependency risk. The change is mergeable with explicit owner follow-up to move validation to the client boundary.

Poem

Twenty-four hours in a tidy stream,
Wins and losses fill the clan’s new screen.
Loading waits, then metrics appear,
Empty games speak plainly and clear.
Stale results fade from view—
Fresh clan numbers come through.
