Web client posts Intl.DateTimeFormat().resolvedOptions().timeZone to
PUT /api/me/timezone after every successful login, register, and
bootstrap when the locally-stored tz_last_sent_at is >7 days old.
Cadence tracked in localStorage keeps the server stateless on the
"is this stale?" check.
Failures swallowed: the server's UTC default + last-known value keep
the scheduler functioning until the next successful attempt. SSR-
safe via the typeof window guard.
For #392 Half B. Companion Flutter change in next commit.

Lands four of the U3 frontend surfaces. Splits T5 because the
dispatch covering everything in one shot crashed the runtime
mid-execution; this is the salvageable half.
- /settings gains three cards alongside Appearance: Profile
(display name + email), Password (current + new + confirm with
client-side mismatch check), API Token (display + copy +
regenerate-with-double-click-confirm). Server error codes map
to clear toasts.
- /forgot-password — public; takes an email and always shows the
success message regardless of whether the email is on file
(mirrors the server's no-enumeration posture).
- Login page gets a "Forgot password?" link below the existing
register link.
- API client functions for the four /me endpoints (changePassword,
updateProfile, getAPIToken, regenerateAPIToken), the SMTP admin
trio (getSMTPConfig, updateSMTPConfig, testSMTPConfig), and the
forgot/reset auth pair (forgotPassword, resetPassword).
Tests for these surfaces + /reset-password page + admin SMTP card
land in T5b (next follow-up).
