Changelog: Unreleased

Added

• API CRUD endpoints for Applications and Databases.
• EAV-style modeling endpoints using platform terms: Tables, Columns, Records, and Values.

  • GET /tables/{id}/records
  • GET /columns/{id}/values
  • GET /records/{id}/values

Changed

• Auth UX: sign-out page now uses a single explicit confirmation message in-page and removes redundant banner duplication.
• API CORS configuration expanded for local development to accept both localhost and 127.0.0.1 origins across ports via explicit origins plus regex.
• Auth frontend behavior clarified around explicit session messaging and sign-in redirection paths.
• API auth dependency moved to OAuth2PasswordBearer token extraction for protected endpoints.
• Databases model simplified to internal metadata (name, slug) and no longer stores external connection fields.
• Databases no longer maintain a foreign key link to applications.

Documentation

• Authentication guide updated with current sign-out confirmation behavior and local dev CORS notes.
• Backlog and release-tracking docs synchronized with current auth feature branch progress.
• Added user documentation for Applications and Databases, including endpoint references and workflows.
