feat(firmware): add flash-FAT storage partition table

Browse Source 
16 MB layout adding a `storage` FAT data partition for the on-device git
working copy. Applied only by `just flash-git-push` (espflash
--partition-table); the editor flash keeps its default single-app layout.

# Typoena partition table — 16 MB flash (ESP32-S3-WROOM-1-N16R8).
#
# Adds a `storage` data partition of subtype `fat` so the on-device git working
# copy (Spike 7) lives on flash-FAT: `esp_vfs_fat_spiflash_mount_rw_wl` finds it
# by the label below and mounts it at /spiflash.
#
# esp-idf-rs does NOT compile this table (it builds `libespidf` as a static lib,
# not a full app project) — espflash applies it at flash time via
# `--partition-table partitions.csv`. Only `just flash-git-push` passes that flag,
# so the editor flash is unaffected and keeps its default single-app layout.
#
# factory is 3 MB — generous headroom for the libgit2-linked binary (the editor
# is ~1 MB; git_push adds Wi-Fi + FAT + libgit2). storage is 4 MB. Total ~7.4 MB.
