The post-rotation brightness ramp targeted a hard-coded 200 (the old default),
which reset whatever the user had chosen via PWR-short-press after every IMU
rotation. Read brightness_get() instead and scale the 4-step ramp (30/60/85/100%)
toward that target.

Adds power_hal_pwr_long_pressed() and power_hal_pwr_released() to the HAL
contract so shared code can implement a hold-to-pair gesture board-agnostically.
- 216: enable the AXP2101 PKEY LONG + POSITIVE IRQs; bump press-off to 8s so a
~3-6s pair hold doesn't trip the hardware shutdown.
- 1.8": synthesize the same long/release edges in software from the polled
XCA9554 EXIO4 level (short-press now fires on release-if-short).
- template: stub the two new functions (no gesture) for new ports.

Replaces the build-flag-driven #ifdef sprawl (~30 blocks across 6 files)
with a small HAL in firmware/src/hal/ and per-board folders under
firmware/src/boards/. Shared code (main.cpp, ui.cpp, splash.cpp) no
longer contains a single `#ifdef BOARD_*` — optional features are
guarded by BoardCaps (runtime) and BOARD_HAS_* macros (compile-time,
inside the board's own files).
Why: lets community contributors port to new ESP32 + AMOLED + touch
combos by dropping in a boards/<name>/ folder + a PlatformIO env,
without touching shared files. See docs/porting/adding-a-board.md.
Highlights:
- New HAL: display_hal, touch_hal, input_hal, power_hal, imu_hal,
board_caps. Each board provides display.cpp, touch.cpp, input.cpp,
power.cpp, imu.cpp, caps.cpp, board_init.cpp + private hardware
drivers (e.g. io_expander.{h,cpp} on AMOLED-1.8).
- PlatformIO build_src_filter selects each board's folder per env.
- ui.cpp picks fonts and layout from board_caps() via compute_layout()
with screen-height breakpoints (>= 460 → large, else compact).
- splash.cpp computes CELL = min(W,H)/20 — responsive instead of two
hardcoded values.
- idle.cpp (from #24) rewired through display_hal + power_hal — no
longer depends on the deleted display_cfg.h / power.h.
- power_hal gains power_hal_is_vbus_in() for idle's
IDLE_SLEEP_WHEN_CHARGING gate.
- boards/template/ + docs/porting/{adding-a-board,hal-contract,
capability-flags}.md to bootstrap new ports.
- display_cfg.h, power.{h,cpp}, imu.{h,cpp}, io_expander.{h,cpp}
deleted from src/ root (moved into boards/<name>/ or hal/).
Verification: both `pio run -e waveshare_amoled_216` and
`pio run -e waveshare_amoled_18` succeed unchanged.
