Wrap members directory page in PageShell. Also expand visual mask
selectors to cover .filter-bar, .skills-bar, and .connections-section
because filter content varies based on dynamic tag/topic state and
async fetch ordering. Rebaselines several existing snapshots that now
mask wider regions but capture the same structural layout.
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.
