feat(providers): add unit tests, ESLint suppressions, and fix hardcoded userid for TinyCMS Web

- Add unit tests for WASM init, UUID validation, challenge flow (15 tests)
- Add WASM source comment explaining binary origin
- Replace hardcoded userid with dynamic provider-specific data
- Add ESLint suppressions for no-explicit-any in WASM bridge code
- Add explanatory comments for DOM shim (runtime WASM-bindgen, not test mocks)
