feat: add cipherSuites option and "unsafe" fingerprint to TLS UI settings

[Copilot]

Adds two missing TLS options from the XTLS TLS spec to the server configuration UI. Mirrors patterniha/v2rayNG#1 for v2rayN.

Changes

• Model: Added CipherSuites property to ProfileItem, cipherSuites field to TlsSettings4Ray
• Core config: V2rayOutboundService now passes cipher suites (colon-separated string → list) to the xray TLS config
• Fingerprints: Added "unsafe" to Global.Fingerprints
• UI (WPF + Avalonia): New "Cipher Suites" text field between ALPN and AllowInsecure, with data bindings
• Resources: Added TbCipherSuites label string

Usage

Users can now specify custom cipher suites as a colon-separated string (e.g. TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256) in the TLS settings panel, and select unsafe as a uTLS fingerprint.

Found and fixed three issues in commit b2a341e → new fix at HEAD:

1. cipherSuites type was wrong — xray-core expects a string (json:"cipherSuites"), not an array. Changed List<string>? → string? in TlsSettings4Ray and updated V2rayOutboundService to pass the string directly instead of converting to a list.

2. Missing ConfigHandler copy — CipherSuites wasn't being persisted when saving/editing a profile. Added item.CipherSuites = profileItem.CipherSuites; alongside the other TLS fields.

3. Verified that sing-box doesn't have this field (correct to omit), and that the share link format doesn't need it (matches v2rayNG approach).

oh you had some mistakes and fixed them, so i think it is better to check again.

Did a full re-check. Found one missing piece: TbCipherSuites wasn't added to the locale-specific .resx files (fa, fr, hu, id, ru, zh-Hans, zh-Hant). Fixed in 1cbbb6c.

Verified everything else is correct:

• cipherSuites is string? in TlsSettings4Ray (matches xray-core's json:"cipherSuites" which is a string)
• V2rayOutboundService passes the string directly (no list conversion)
• ConfigHandler copies the field on save
• REALITY settings correctly omit it
• Share link format correctly omits it (not part of the standard URI spec)
• UI bindings and grid rows are consistent in both WPF and Avalonia

again you had a mistake, if needed check again.

Found the issue: txtCipherSuites wasn't being disabled for Hysteria2 and Naive protocols (where cmbAlpn and cmbFingerprint are also disabled since those protocols handle TLS differently). Fixed in the latest commit — added txtCipherSuites.IsEnabled = false for both protocols in both WPF and Avalonia code-behind.
