- emailHour, emailMinute, emailDayOfWeek, emailTimezone in SettingsValues

- Mail adapter (src/app/mail.ts) with Mail.register/unregister that sends
PUT/DELETE /subscription/email to mailship with NIP-98 auth
- UI: frequency toggle (daily/weekly), HH:MM time input, day-of-week picker
(shown only for weekly), surface mailship errors via toast

This PR implements video thumbnails for `.mov`, `.webm`, and `.mp4` files in the `ContentLinkBlock` component.
Changes:
- Added the `poster` attribute to the `<video>` tag.
- Set the poster source to `{url}#t=1` to capture a clear preview frame at the 1-second mark.
- Verified locally that thumbnails are now correctly displayed instead of a black/empty box.
Closes#73
