Favicon, SMTP and misc updates

Favicon:
- Replaced HTML tokenizer, much faster now.
- Caching the domain blacklist function.
- Almost all functions are async now.
- Fixed bug on minimizing data to parse
- Changed maximum icon download size to 5MB to match Bitwarden
- Added `apple-touch-icon.png` as a second fallback besides `favicon.ico`

SMTP:
- Deprecated SMTP_SSL and SMTP_EXPLICIT_TLS, replaced with SMTP_SECURITY

Misc:
- Fixed issue when `resolv.conf` contains errors and trust-dns panics (Fixes #2283)
- Updated Javscript and CSS files for admin interface
- Fixed an issue with the /admin interface which did not cleared the login cookie correctly
- Prevent websocket notifications during org import, this caused a lot of traffic, and slowed down the import.
  This is also the same as Bitwarden which does not trigger this refresh via websockets.

Rust:
- Updated to use v1.59
- Use the new `strip` option and enabled to strip `debuginfo`
- Enabled `lto` with `thin`
- Removed the strip RUN from the alpine armv7, this is now done automatically
