fix(sensecap_solar): correct TX LED after remap & power-button pin changes

[Confituurke]

Updates the SenseCap Solar build flag P_LORA_TX_LED from 11 to 12 so LoRa TX activity is driven on the blue LED again, consistent with variants/sensecap_solar/variant.h (LED_BLUE / PIN_LED on pin 12).

SenseCap Solar LED GPIO definitions were corrected in #1689 . A later power-button–related pin mapping change e323755 , #1873 updated board wiring, but P_LORA_TX_LED changed to 11, which maps to LED_WHITE in the current headers and caused drift between the forks. That made the white LED blink on TX, which looks like a white/blue swap even though the underlying problem was the TX LED build flag not matching the updated LED pin macros.

@ripplebiz & @liamcottle FYI and approval; so these don't get changed/overwritten in another future PR.

@Specter242 FYI; since you initiated PR #1873

Thank you

Thanks, this seems like it works better.

Rebased to version 1.15.0 dev-branch

Something doesn't seem quite right with this, can youchange the white LED setup in SenseCapSolarBoard::begin() so that it's not permanently lit?

Thanks for your work on this everybody 👍
