Kaj SchittecatandClaude Opus 4.8 4e6a9e0108 touch: beta_49 - T-Display P4 fixes (exit traps, screen timeout, UI scale, GPS, control center)
P4-focused beta. Non-P4 boards only pick up minor shared exit-trap code, nothing user-facing.

- Snake + full-screen apps (Monitor/Spectrum/Discover/Web mirror/Advert) exit on status-bar tap
- Screen timeout / standby / burn-in dimming wired for the AMOLED (setBrightness path)
- UI scale pinned to 100% on the P4 (text overflow above 100%)
- No hard-lock on screen-off (P4 has no lock screen yet)
- GPS: L76K detect at 9600 baud, skip boot-detect race, 4096 RX buffer
- Control center dropdown taller on tall screens so the GPS line clears the toggle buttons
- P4 LCD SKU: HI8561 backlight PWM on GPIO51 (fixes the black screen)

# beta_49 - T-Display P4 only
# One user-facing note per non-blank, non-# line; # lines are section comments.
This beta only has T-Display P4 fixes. If you run any other board there is nothing new for you here, stay on beta_48.
# Fixed (T-Display P4)
The Snake game no longer traps you. Tap the top bar to leave it. Before, the only way out was a reset.
The full-screen tools (Monitor, Spectrum, Discover, Web mirror, Advert) can now be left by tapping the top bar, so they no longer trap you either.
The screen timeout now works. The display turns off after your idle time and wakes on touch. This also fixes standby and burn-in dimming.
Text no longer overflows its boxes. The interface is pinned to the 100% size that fits the panel.
GPS: the L76K module is now found reliably and read at 9600 baud. You still need the GPS antenna connected and a clear view of the sky to get a fix.
The control center dropdown is taller so the GPS status line sits below the buttons instead of behind them.
P4 LCD model only: fixed the black screen. The backlight now turns on. Please test and report.
