feat(e2e): Playwright suite — 134 tests across 9 spec areas + UA matrix

Adds an end-to-end Playwright test suite under e2e/ that spins up an isolated docker-compose stack (Postgres :55432, Caddy :3101, backend with EVENTSNAP_TEST_MODE=1, SvelteKit adapter-node frontend) and exercises the SvelteKit app against the real Rust backend. Phase 1 — happy paths covering every documented USER_JOURNEYS.md flow: 01-auth/ join, recover, admin login, leave event, PIN lockout 02-upload/ gallery picker (API path), rate-limit + admin toggle 03-feed/ like/comment SSE, filters, SSE reconnect on visibility 04-host/ event lock API, ban/unban, promote 05-admin/ config validation, foundational authz guards, stats 06-export/ /export status + download stub __smoke/ cross-UA happy-path (runs on every UA project) Phase 2 — adversarial + browser chaos: 07-adversarial/ XSS payloads (6 × display name path), SQLi shapes, length / encoding / RTL override / NUL byte; file-upload boundaries (ELF body claimed as JPEG, oversize vs max_image_size_mb, zero-byte, NUL filename, path-traversal, SVG-with-script); JWT alg:none, signature/payload tamper, expired session, PIN brute-force (serial + parallel), admin password brute-force; deep authz (cross-user delete, banned user across like/comment/feed-read, host→admin escalation); small-scale DDoS (20× /join, 10MB comment body, 10 concurrent SSE). 08-browser-chaos/ localStorage / sessionStorage / cookie purge, IndexedDB drop mid-session, offline → reconnect, slow-3G, 503 flakes, 429 with no retry storm, multi-tab same/different user, no-JS, hostile CSS, clock skew ±1h / -2d, localStorage quota exhausted. Phase 3 — mobile gestures (runs only on chromium-mobile / Pixel 7): 09-mobile/ touch-target ≥44px audit, env(safe-area-inset-bottom) structural check, long-press (FeedListCard → ContextSheet, quick-tap negation, click-suppression), double-tap (feed card like + lightbox heart-burst, via synthetic pointer events to bypass the first-tap-fires-click trap), viewport reflow (portrait/landscape/narrow/phablet), plus fixme stubs documenting planned gestures (swipe lightbox L/R, swipe-down dismiss, pull-to-refresh, long-press-comment). Cross-UA matrix (chromium-engine projects run @smoke only): chromium-pixel7, chromium-galaxy-s22, samsung-internet (Samsung UA emulation on Galaxy viewport), edge-android, plus webkit-iphone, chrome-ios, firefox-android, firefox-desktop — the latter four need libavif16 on the host (Playwright dep) but the configs are in place. Infrastructure: - fixtures/test.ts central test.extend (api, db, adminToken, guest, host, signIn). Per-test DB truncate via the dev-only POST /admin/__truncate route, gated by EVENTSNAP_TEST_MODE=1. - helpers/sse-listener.ts, helpers/upload-client.ts (Node-side multipart for adversarial file-upload tests + JPEG/PNG/ELF magic constants), helpers/touch.ts (longPress / doubleTap / swipe / inlineStyle / computedStyle). - 10 page objects covering every route + UploadSheet/Lightbox. - global-setup waits for /health, logs in admin, disables every rate-limit and quota toggle. - .github/workflows/e2e.yml: PR check runs chromium-desktop + the smoke matrix in parallel, uploads playwright-report/ and traces on failure. Findings the suite surfaces as live `[finding]` warnings (not silenced): 1. /admin/login has no rate-limit or lockout (bcrypt cost only). 2. PIN-attempt counter races under parallel /recover requests. 3. Zero-byte uploads pass /api/v1/upload. 4. SVG-with-script can pass the magic-byte check (consider CSP + X-Content-Type-Options on /media/*). Stack-internal docs live in e2e/README.md (UA tier table, Samsung Internet escalation tiers A/B/C, debugging tips, roadmap). Final tally: 134 passed / 0 failed / 9 skipped (test.fixme stubs for not-yet-shipped gestures and one UI-upload-flow investigation).
