Schematizing: Add Request/Response schemas to everything

[matt-taylor]

• Additional schemas
• update testing matrix
• Minor nits for Auth JWT

---

Note

Major schema refactor and platform upgrades with improved auth handling.

• Introduces namespaced shared/, entities/, and endpoint-specific request/response schemas; removes legacy plain_text/ and old inbox schemas; updates schema.rb requires
• Updates controllers (Auth, User, Admin, Inbox) to use new schemas; adds GET /auth/login/identifier/valid and switches user serialization to Shared::User
• Strengthens Authorization: header renamed to Authorization with strict Bearer <token> parsing and new error messages; updates spec helper and adds tests for malformed headers
• Services refactored to emit new schema types; pagination now returns Shared::Pagination/Page and helper ensures empty pagination hash when nil
• Config: expands default user attributes shown; aligns naming to Shared::User
• Upgrades runtime/tooling: Ruby 4.0.1, Bundler 4.0.4, Rails ~> 8, refreshed gem versions; CI matrix adds Ruby 3.4.8/4.0.x; Docker/Docker Compose updated
• Bumps gem version to 0.5.0
