Pull request overview

This PR upgrades the application’s runtime and framework versions (Ruby/Rails) and refreshes the dependency lockfile to match, along with updating version pins used by local tooling/docs.

Changes:

• Bump Ruby from 3.3.6 to 4.0.1 across .ruby-version, .tools-versions, and docs.
• Bump Rails from 7.x to 8.1.3 and update Gemfile.lock accordingly (including related gem upgrades/removals).
• Remove the nested room_tickets resource route under rooms (leaving the explicit send_email_for_tdx_ticket route in place).
