chore: release v0.23.9

Settings -> DX Cluster: a toggle and an interval. When it is on, logging a QSO
announces the station on the master cluster — the QSO's own station callsign as
the DX, on the frequency the contact was made on — so callers find the run
without waiting for someone else to spot it. The node fills the DE field from
the login, so the spotter is us too: a self-spot.

It fires on the FIRST QSO of a frequency and then at most once per interval.
Both halves matter: announcing every QSO would flood the node and get the
station filtered out, while a pure timer would stay silent for minutes after a
band change. A drift of up to 500 Hz still counts as the same run, so nudging
the VFO mid-pileup does not re-announce.

Five minutes is the floor, clamped in SaveSelfSpotSettings as well as in the
input: the limit protects the node from us, so it must not depend on the
frontend. The interval input keeps raw text and clamps on blur — clamping per
keystroke rewrote "10" to "5" as soon as the "1" landed.

Wired into both log paths (manual entry and UDP auto-log) on the async side, so
a cluster that is slow or down never holds up logging. A send failure restores
the previous throttle state, so the next QSO retries instead of sitting out an
interval that produced no spot.

+  Country, DXCC and CQ/ITU zones from `cty.dat`, overriding the file. Corrects
+  what contest software exports wrong (e.g. RG2Y tagged Asiatic instead of
+  European Russia). ClubLog's date-ranged DXpedition overrides are applied on top
+  per QSO date (e.g. TO2A in 2012 → French Guiana) whenever the ClubLog data is
+  downloaded. Everything else in the ADIF is kept as-is. *Tip: combine with
+  **Update duplicates** to re-fix QSOs already in your log.*
+- **Fill my station fields from my profile** *(off by default)* — backfill empty
+  `MY_*` fields (grid, rig, antenna, address, city, state, county, SOTA/POTA ref,
+  TX power…) plus Operator and Owner callsign from the active profile. Existing
+  values are kept; only `STATION_CALLSIGN` is left untouched so a mixed-call log
+  isn't re-routed. It **also** stamps your default confirmation statuses (paper
+  QSL, LoTW, eQSL, Club Log, HRDLog, QRZ.com — sent & received) on QSOs the file
+  leaves empty. Enable when importing **your own** log; leave off for someone
+  else's.
+
+### Field remapping (move fields on import)
+
+Contest software stores the exchange where its own module keeps it. The RSGB IOTA
+contest, for example, exports the island reference in `STATE` — imported as-is it
+becomes a US state and the IOTA award stays empty. Click **"The file puts a field
+in the wrong place…"**, then add a `STATE → IOTA` row (add as many rows as you
+need). The destination is filled **only where the file left it blank**.
