Add Insomnia export and dynamic hostname for API doc

Insomnia export (/api/doc/insomnia.json):
- Generates Insomnia v4 export format with all API routes
- Workspace with environment variables (base_url, env, email, password, jwt_token)
- Folders per section (Auth, Events, Categories, Billets, Scanner)
- Each request with correct method, URL with Insomnia template vars, headers, body
- Auth routes use base_url directly, others use base_url/api/{env}/...
- Download button (indigo) next to Spec JSON button

Dynamic hostname:
- Insomnia export uses request.getSchemeAndHttpHost() (not hardcoded)
- Template passes host via data-host attribute
- JS env switcher reads host from data-host or falls back to location.origin
- Base URLs update dynamically when switching sandbox/live
