Josh Knapp 2c341e8cea Add index page with URL generator and remove passphrase from display ...

Created a beautiful landing page with random room/passphrase generation
and updated security model for read-only access.

New Files:
- server/php/index.html: Landing page with URL generator

Features:
- Random room name generation (e.g., "swift-phoenix-1234")
- Random passphrase generation (16 chars, URL-safe)
- Copy-to-clipboard functionality
- Responsive design with gradient header
- Step-by-step usage instructions
- FAQ section

Security Model Changes:
- WRITE (send transcriptions): Requires room + passphrase
- READ (view display): Only requires room name

Updated Files:
- server.php:
  * handleStream(): Passphrase optional (read-only)
  * handleList(): Passphrase optional (read-only)
  * Added roomExists() helper function

- display.php:
  * Removed passphrase from URL parameters
  * Removed passphrase from SSE connection
  * Removed passphrase from list endpoint

Benefits:
- Display URL is safer (no passphrase in OBS browser source)
- Simpler setup (only room name needed for viewing)
- Better security model (write-protected, read-open)
- Anyone with room name can watch, only authorized can send

Example URLs:
- Client: server.php (with room + passphrase in app settings)
- Display: display.php?room=swift-phoenix-1234&fade=10&timestamps=true
