SO2R: two radios in one instance (#46) (#137)

* Spec: SO2R with two radios in one instance (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Plan: SO2R implementation (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Move the rotator command rules into RotatorControl (#46)

Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

* Store the SO2R switch, the second Win-Test station and rotator 2 (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Route frequency reports to radio 1 or 2 (#46)

Add the RadioSlot enum (FIRST, SECOND) with its QRG and QTF targets, and
the pure RadioSlotRouter that decides per RadioInfo packet and per
Win-Test station which radio a report belongs to.

* Send RadioInfo of radio 2 to SECONDQRG when SO2R is on (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Send Win-Test STATUS of the second station to SECONDQRG when SO2R is on (#46)

* Run a second PSTRotator for radio 2 with SO2R (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Start rotator 2 only while an ON4KST session runs (#46)

* Settings for SO2R, the second Win-Test station and rotator 2 (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Turn antenna 2 and show QTF2 with SO2R (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Make the SO2R switches observable so Apply shows them (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Document SO2R (#46)

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Refuse clashing PSTRotator ports in both directions (#46)

Writing either port now checks same-or-adjacent against the drafted value of
the other; rotor 1 is only checked while SO2R and rotor 2 are on. Also fixes
a misplaced Javadoc, stale WinTest parseStatus Javadoc, docs wording and
removes an unused import and dead comment.

* Remove the executed SO2R plan (#46)

The plan's content lives on in the commits, the spec and PROJECT_CONTEXT.
