Settings › Radio and Tools › Repeater had near-identical preset-picker
logic (name/list-index lookup, save/delete, popup build, selection
handling) plus their own copy of the nearest-bandwidth search — only the
target fields (companion params vs. dedicated repeater profile) and the
apply call differed.
Extract the shared logic into RadioPresetPicker (a Target of field
pointers + a Result the screen acts on), with no dependency on UITask so
each screen keeps its own apply/dirty/keyboard/alert handling. Move the
nearest-bandwidth search to nearestBwIndex() in RadioPresets.h. Removes
~6 duplicated methods and 4 state fields from each screen.
Verified: WioTrackerL1_companion_solo_dual builds clean.

Settings > Radio gains a repeater toggle, 16 community-suggested radio
presets plus manual Freq/SF/BW/CR tuning (digit-by-digit Freq editor),
4 persisted user preset slots, and the packet pool bumped 16->32 so
queued retransmits stop starving incoming-packet allocation while
relaying.
Four opt-in politeness knobs (skip-advert, max-hops, yield, min-SNR),
all flood-only and off by default, plus overhear suppression that
cancels a queued retransmit if a peer relays the same packet first.
Adaptive Power Control is suppressed while relaying (pins TX power to
the ceiling) and duty-cycle RX is forced off, since a repeater needs
to hear and relay at consistent power.
A dedicated Tools > Repeater screen consolidates the toggle, the
politeness knobs, and live forwarding stats, plus an optional "Custom"
radio profile — a dedicated frequency/SF/BW/CR for relaying, separate
from the companion's own network, band-matched to the companion
frequency by default and used everywhere a radio change can happen
(boot, on-device toggle, app-driven CMD_SET_RADIO_PARAMS, Settings
radio edits) so the device never silently falls back to the wrong
params mid-relay.
Diagnostics gains the actually-forwarded packet count, real heap-free
via mallinfo(), a reset-counters popup, and hardened loop-detect
bounds. Also: a frequency-floor fix and a float-equality preset-match
fix in the repeater profile logic, deduped BW-table/valCol/profile-
seeding helpers shared between Settings and the Repeater screen, and
a build.sh fix tolerating control characters in `pio project config`'s
JSON dump.
