Position sharing was opt-out (the default primary channel shipped
position_precision=13) while device telemetry was already opt-in, and a
normal firmware upgrade preserves saved config, so existing nodes stayed
position-on. This makes both broadcasts opt-in, both on a fresh flash and via
a one-time migration for upgrading nodes.
- Fresh default: initDefaultChannel now sets position_precision=0.
- One-time migration in loadFromDisk, gated on a dedicated
POSITION_TELEMETRY_OPTIN_VER (26) watermark kept separate from
DEVICESTATE_CUR_VER (bumping that would re-run the NodeDatabase v24
legacy decoder on already-migrated v25 DBs): disables position broadcast
on PUBLIC/default-PSK channels and forces every device-telemetry
mesh-broadcast flag plus the MQTT map-report location off.
- Private-PSK channels are left untouched: a channel with a custom key is a
deliberate trusted-group setup, so its configured precision is preserved.
- Idempotent: ordinary saves never re-stamp .version, so a user who
re-enables sharing is not re-disabled on the next boot.
- Added pure channelFileUsesPublicKey() (operates on the raw ChannelFile,
since the channels singleton isn't initialized during loadFromDisk) and
refactored Channels::usesPublicKey() to delegate to it.
- New test/test_optin_migration native suite (14 cases).
