v1.0.1-beta.9

feat: add console controller tabs and DiGiCo control group support

- Console page now has three full-screen tabs: Inputs, Control Groups, Aux Outputs
- Each tab fills the entire screen height giving faders maximum travel
- Aux Outputs tab switches from horizontal scroll to a full-width vertical list
- Control Groups section added: vertical fader strips (teal accent) for all 8 CGs
- CG fader, mute, and solo send to /Control_Groups/N/fader|mute|solo on desk
- Server polls desk for CG state on console page load and caches CG names
- Also includes -0.5 dB cut button in monitor aux headers (from previous commit)
