Add PLAYWRIGHT_PORT env var to playwright.config.js so a worktree can run
its own dev server on a different port without disrupting the main dev
server. Rebaseline connections-mobile-auth which had drifted from the
suggestions data state captured during Phase 1.
Add aria-labels to form controls (selects, checkboxes, switches), set
html lang attribute and page title, fix color contrast for --candle-dim
and --text-faint tokens, underline inline links, remove opacity hack.
Harden dev login endpoints with atomic findOneAndUpdate and tokenVersion
in JWT. Update Playwright timeouts and E2E test helpers.
