FTPS TLS session reuse, rustls migration & server badge overhaul

Fixed

• FTPS TLS session reuse (Issue [#78]): Servers requiring TLS session resumption (CerberusFTP, vsftpd require_ssl_reuse=YES, FileZilla Server, ProFTPD) now work correctly. Migrated TLS backend from native-tls to rustls, which automatically caches and resumes TLS sessions on data connections per RFC 4217. Previously failed with 522 SSL connection failed: session reuse required
• Saved server host:port duplication: Servers saved with non-default ports (e.g. 2121) had the port appended to the hostname, causing host:port:port double-port errors on reconnect. Backend now strips port suffix from hostname, and frontend no longer concatenates host:port in saved server params
• FTP TLS mode not applied from saved servers: Saved FTP connections with "Require explicit FTP over TLS" would reconnect as plain FTP because tls_mode defaulted to undefined instead of explicit. Both buildProviderParams paths now default FTP protocol to explicit TLS
• Missing common.duplicate i18n key: Added missing translation key that caused infinite warning loop in console. Propagated and translated across all 47 locales

Improved

• Server card protocol badges: FTP/SFTP/FTPS badges now color-coded - FTPS emerald green, SFTP teal, plain FTP amber. Previously all gray
• Server card TLS security indicator: Shield icon (green) shown for verified TLS/SSH connections, alert triangle (gray) for connections with certificate verification disabled
• TLS mode persistence: Encryption dropdown default (explicit for FTP, implicit for FTPS) now persisted on save even when the user doesn't touch the dropdown

Changed

• TLS backend: Replaced native-tls (OpenSSL/SChannel/SecureTransport) with rustls for FTP/FTPS connections. Enables TLS 1.3 session tickets and TLS 1.2 session ID resumption. Cross-platform pure-Rust implementation with no system OpenSSL dependency for FTP
