Commit Message

fix: handle ActionController::UnknownFormat with 406 response

Adds rescue_from handler for ActionController::UnknownFormat in ApplicationController,
returning 406 Not Acceptable for unsupported request formats.

This is the idiomatic Rails approach for handling format negotiation errors,
as documented in the Rails Guides and API:
- https://api.rubyonrails.org/classes/ActionController/MimeResponds.html
- https://github.com/rails/rails/blob/main/guides/source/action_controller_advanced_topics.md

Changes:
- Add rescue_from ActionController::UnknownFormat to ApplicationController
- Add render_not_acceptable method returning 406 status
- Add not_acceptable.html.haml error template
- Add comprehensive controller tests for HTML, JSON, and XML formats

Fixes UnknownFormat errors when crawlers/scripts send non-HTML Accept headers.
