Power2All/torrust-actix v4.2.21 on GitHub

What's Changed

Bumped versions.
Dropped the unmaintained rustls-pemfile (RUSTSEC-2025-0134) for the PEM support already in rustls-pki-types; TLS key files may now be PKCS#8, PKCS#1 or SEC1 everywhere, including the cluster master.
Security: /scrape without a key is now refused when keys_enabled is set, matching /announce.
Security: cluster WebSocket connections that never complete the handshake are dropped after 30 seconds instead of holding a connection slot forever.
Fixed two lifetime bugs and an alignment bug in the Windows RIO receive backend.
The UDP hot path no longer builds a Sentry transaction per datagram when tracing is off.
hex2bin rejects over-long input instead of silently truncating it to the first 20 bytes, and no longer reports malformed client input to Sentry.
The announce path no longer aborts the process when the system clock sits before the UNIX epoch; it now uses the shared current_time() helper.
