Adapted for OHOS

[FrankHan052176]

Summary by CodeRabbit

• Bug Fixes
  • Improved OHOS compatibility by aligning configuration paths, ID/key generation, and network/TLS behavior with the platform’s available TLS support.
  • Updated websocket TLS connector handling and disabled OHOS cert-validation relaxation/retry logic where not supported.
  • Fixed HTTPS proxy TLS handling for OHOS and adjusted TLS cache behavior accordingly.
  • Standardized OHOS fingerprinting to use a consistent placeholder address.
  • Narrowed Linux-only IPC/system logic so it won’t run on OHOS.
• Maintenance
  • Updated cryptography dependency source and refined platform-target dependency selection for TLS/websocket support.

📝 Walkthrough

Walkthrough

This PR adds target_env = "ohos" conditional compilation across dependency selection, config and ID handling, fingerprinting, top-level exports, platform gating, TLS connection paths, and TLS cache handling.

Changes

OHOS Platform Support

Layer / File(s)	Summary
Dependency selection for OHOS builds Cargo.toml	Switches sodiumoxide to the upstream git dependency, splits TLS dependencies by target, and excludes OHOS from a Linux-only dependency section.
Config paths, IPC directories, and IDs src/config.rs	Updates OHOS handling in config paths, IPC directory selection, log paths, online-state gating, and ID generation while excluding OHOS from Linux-only branches.
Fingerprinting, exports, and platform gates src/fingerprint.rs, src/lib.rs, src/platform/mod.rs	Zeros fingerprint addresses for OHOS, adjusts export and get_uuid() guards, and excludes Linux platform code from OHOS builds.
Proxy TLS dispatch and fallback src/proxy.rs	Restricts native-TLS proxy code to non-OHOS targets, routes OHOS NativeTls connections through rustls, and makes OHOS fallback log and bail instead of retrying native-TLS.
Websocket TLS connector and retry gating src/websocket.rs	Builds rustls connectors on OHOS, gates native-TLS-specific code, and removes invalid-certificate retry branches from OHOS builds.
OHOS TLS cache handling src/tls.rs	Skips TLS cache updates when OHOS uses NativeTls.

- Line 36: Pin the forked sodiumoxide dependency in Cargo.toml by replacing the
floating branch reference with a fixed rev or tag, and if this fork is only
needed for OHOS, move the dependency entry into the OHOS target-specific section
instead of keeping it global. Locate the existing sodiumoxide dependency
declaration and update it so builds use a stable, reproducible source.

Since the upstream sodiumoxide is archived, I had to fork it to make the necessary adaptations for openharmonyos via a git link.
Here is my fork: https://github.com/FrankHan052176/sodiumoxide
To make it easier to maintain, would it be possible to move this fork directly into the rustdesk-org organization? I'm happy to transfer it if you agree.
