feat(reticulum): enable transport mode + switch to LittleFS adapter

Browse Source 
Two adjustments to setup_reticulum() / setup_filesystem():

1. `Reticulum::transport_enabled(true)` — unlocks the path-store
   init block at Transport.cpp:244 that was gated behind transport
   mode. Without it, _new_path_table.put() always returned false at
   TypedStore::isValid() (no filesystem assigned), every announce
   surfaced as "Failed to add destination" spam, and the UI's
   announce list stayed empty. Transport mode also enables relaying
   for other nodes — tolerable on a T-Deck Plus with PSRAM headroom
   and LittleFS-backed path persistence.

2. Switch the microStore adapter from SPIFFSFileSystem to
   LittleFSFileSystem (paired with -DUSTORE_USE_LITTLEFS in
   platformio.ini). LittleFS handles sustained writes; SPIFFS GC
   stalls were causing every path-store put to fail.
