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

<!-- FAQ -->
<div class="section">
<h2>Frequently Asked Questions</h2>
<h3 style="color: #667eea; margin-top: 20px;">How many users can join one room?</h3>
<p>Technically unlimited, but we've tested up to 20 users successfully. Each user gets a unique color.</p>
<h3 style="color: #667eea; margin-top: 20px;">Is my passphrase secure?</h3>
<p>Yes! Passphrases are hashed using PHP's password_hash() function. They're never stored in plain text.</p>
<h3 style="color: #667eea; margin-top: 20px;">How long does a room stay active?</h3>
<p>Rooms are automatically cleaned up after 2 hours of inactivity to save server resources.</p>
<h3 style="color: #667eea; margin-top: 20px;">Can I use custom room names?</h3>
<p>Yes! You can use any room name you want instead of the randomly generated one. Just make sure all team members use the exact same name.</p>
