feat(web): overhaul SPA to look like a proper IRC client

Major UI overhaul of the embedded web SPA to match traditional IRC client
look and feel:

Layout changes:
- Input bar now spans full width at bottom of window (below user list)
- Removed inline join dialog from tab bar (use /join command instead)
- Nick prefix shown in input bar (e.g. 'alice>')
- Topic bar shows 'Topic:' label with accent color

IRC command support:
- Added /me command (action messages via meta.action flag)
- Added /mode command for channel/user mode changes
- Added /quit command for clean disconnect
- Added /help command listing all available commands
- /part now accepts optional reason message

User list improvements:
- Parse 353 RPL_NAMREPLY to extract user mode prefixes
- Display @nick for ops, +nick for voiced, plain for regular users
- Sort users by mode rank: ops first, then voiced, then regular
- Ops shown in orange, voiced in green, regular in default color
- Extracted UserList into dedicated component

Message display:
- Messages displayed inline with nick on same line (IRC style)
- Action messages (/me) shown as '* nick does something' in purple
- System messages prefixed with '***'
- Uses IRC vocabulary: 'has parted' instead of 'has left'
- Parse 332 RPL_TOPIC for channel topic on join

UX improvements:
- Command history with up/down arrow keys (100 entries)
- Input always visible including on Server tab
- Dark theme with monospace font (JetBrains Mono/Fira Code)
- Hover highlight on messages
- Custom scrollbar styling
- Tab type-based styling (server tab bold)
