Port Venice web subscription credits

[Finesssee]

Summary

• Port the upstream 0.61.0 Venice Web subscription-credit source behind an explicit web usage setting.
• Rebuild only the allowlisted Venice session cookie, reject incomplete/duplicate/control-character/oversized cookie material, and validate the session JWT expiration and credit claims without persisting credentials.
• Project subscription credits, cycle usage, refill, cap, next refill, and plan as transient display details through the shared carrier from PR Add transient provider detail carrier #564.

Validation

• cargo test --manifest-path rust/Cargo.toml --lib providers::venice::tests
• cargo test --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml commands::tests::venice_display_details_map_to_the_bridge_without_identity
• cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
• cargo clippy --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml --all-targets -- -D warnings
• git diff --check

Frontend Vitest was not run because the worktree intentionally has no node_modules; no dependency install was performed.
