liu weikai 400c5ed996 fix(esp): reduce RAM pressure and TDeck display stalls

Tune Arduino task stacks and board env flags to recover internal RAM for BLE startup.

Avoid synchronous boot UI rendering on Arduino loopTask and move large board singletons toward PSRAM where available.

Improve TDeck/Pager display responsiveness by restoring practical LVGL DMA buffers, using SPI pixel writes, disabling transition animations, and testing TDeck display SPI at 80MHz.

`boards/tab5`

Board-owned home for Tab5 support and board-specific ESP adapters.

Current extracted board profile and verified M5-Bus routing for the Tab5 target:

Capabilities: display, touch, audio, SDMMC, GNSS, RS485, M5-Bus LoRa module routing
System I2C / M5-Bus sensor bus: port 0, SDA=31, SCL=32
Port A / Grove I2C: port 1, SDA=53, SCL=54
Module GNSS UART: UART2, TX=6, RX=7, 38400
Module GNSS sensor bus: shared SYS I2C on 31/32
RS485 UART: UART1, TX=20, RX=21, DE=34
SDMMC: D0=39, D1=40, D2=41, D3=42, CMD=44, CLK=43
ESP32-C6 SDIO2 link reference: CLK=12, CMD=13, D0=11, D1=10, D2=9, D3=8
ESP32-C6 reset reference: GPIO54, requires validation before runtime use because the current board profile also records GPIO54 as Port A / Grove I2C SCL
Audio I2S: BCLK=27, MCLK=30, WS=29, DOUT=26, DIN=28
Motion sensors: BMI270+BMM150
M5-Bus LoRa SPI host: SPI3_HOST (2 in ESP-IDF spi_host_device_t enum)
M5-Bus LoRa SPI: SCK=5, MISO=19, MOSI=18
M5-Bus LoRa control: NSS=35, RST=45, IRQ=16, BUSY=-1, PWR_EN=-1
Power note: M5-Bus modules are powered from the shared external 5V rail; there is no dedicated per-module PWR_EN GPIO in the current board profile
LCD backlight: 22
Touch interrupt: 23

Important routing notes:

53/54 are the Tab5 Port A / Grove pins, not the M5-Bus GNSS UART pins.
Tab5 Module GNSS on M5-Bus uses shared SYS I2C on 31/32 for onboard module sensors and a switched UART route for GNSS NMEA/UBX data.
The currently adopted GNSS UART route is TX=6, RX=7, matching the verified M5-Bus routing used in the Tab5 GNSS integration reference.
The current LoRa route assumes an M5-Bus module wired to NSS=35, IRQ=16, RST=45 with fixed SPI on 5/18/19.

Current responsibilities:

provide Tab5 board/runtime handles for the selected IDF target shell
bind AppContext into the Tab5 IDF app shell
keep Tab5-specific pin/capability knowledge in boards/tab5/board_profile.h
own Tab5-specific runtime glue under boards/tab5/* rather than platform/esp/boards/*
describe C6 and motion-sensor hardware facts without deciding BLE facade, Team Mode, or display-orientation product policy
