feat: register Workspace Profiles as Decodal values (T-710)

Project the evaluated Workspace Profile value into a revision-bound JSON archive without source-path registration or Decodal re-evaluation. Preserve partial-value omissions and explicit overrides, validate before save, and reject legacy registrations with a documented explicit migration.

Fix array-element schema completion and provide fingerprint-bound authoring shapes independently of materialization defaults. Carry metadata through REST, regenerate TypeScript/OpenAPI/WASM artifacts, and exercise save/projection/Runtime consumption and persisted Manifest restore boundaries.

Validation: root cargo check; cargo test -p config-source; cargo test -p worker-runtime; cargo test -p server-api --features typescript; focused profile_settings/value_profiles/archive tests; 39 web config-source/profile API tests; deno task check; cargo fmt --all -- --check; git diff --check HEAD.

Full workspace-server test: 641 passed, one pre-existing ticket_checker_suppresses_stale_and_clean_results_and_diagnoses_invalid_output assertion failure. The same filter fails at base 3c424fd17d in a separately archived source tree and isolated target directory. Remaining server crate tests pass with only that filter skipped (641 lib + 11 bin); unrelated checker code is unchanged.
