feat(mcp): store MCP tokens as SHA-256 hashes instead of plaintext

Replace plaintext token storage with SHA-256 hashes so leaked database
contents cannot be used to authenticate. Plaintext is generated, shown
once at creation time, and never persisted.

- Add `hash_token()` helper and `MCPTokenManager.create_token()` that
  returns `(instance, plaintext)`.
- Replace `token` field with indexed `token_hash`; look up bearers by
  hashing the incoming value.
- Update dashboard, management command, and admin to surface plaintext
  only at creation. Disable admin "add" since it cannot reveal plaintext.
- Migration drops the old `token` column and adds `token_hash`;
  pre-existing tokens are invalidated and must be reissued.
