[bennyfactor]

Upgrades the app’s core Rack/Sinatra stack to Sinatra 4.x + Rack 3.x and adjusts error handling/tests to maintain JSON API behavior under the new response/header APIs.

Changes:

• Bump sinatra to ~> 4.0 and rack-protection to ~> 4.0, with corresponding Gemfile.lock updates (Rack 3.2.x, Sinatra 4.2.x, etc.).
• Update error handlers to use Rack 3-compatible response access (response.content_type, and body handling for array vs string).
• Add request specs for API JSON error responses and multipart upload behavior.
