[feat](trx-frontend-http): improve mobile UX and fix S0/S9 label offset

Browse Source 
- Add viewport meta tag so mobile browsers use device width instead of
  the default 980px desktop viewport
- Add 520px breakpoint: remove controls-tray forced min-width (was
  52–58rem, causing horizontal scroll on phones), stack controls-row
  into a single column with jog wheel first (order: -1)
- Scale frequency DSEG14 display with clamp() on narrow screens
- Make volume sliders responsive width with larger 20px thumb
- Raise spectrum Set/Auto button and input heights to 2.2rem (overrides
  the min-height: 0 that blocked the existing 760px touch-size rule)
- Add overflow-x: auto + flex-shrink: 0 to sub-tab-bar so all six
  plugin tabs are reachable on small screens without clipping
- Swap spectrum hint text based on input device: mouse/keyboard hint
  hidden on touch devices, touch-specific hint shown instead
- Offset S0/S9/S9+ signal history labels 6px below their grid lines
