docs(wiki): cover the recent work, with worked examples

Asked for the wiki to catch up, and to be explicit — examples rather than
descriptions. New page and six rewritten sections.

Recent QSOs and Filters, the page named in the request: the right-click menu is
now a table of what every entry does, and the filter builder has five worked
multi-criteria filters written out field by field, each ending in what you then
do with the result. Including the distinction that prompted it — "export
selected" takes the highlighted rows, "export filtered view" takes every QSO the
filter matched, and after building a filter it is the second one you want. Plus
the traps: ADIF date format, and "is empty" not being "equals N".

Connections (new): the page for a settings section that had none. What OpsLog
listens to and sends, which outbound row another logger actually wants — a
logger asking for "WSJT-X UDP" discards a bare ADIF record — the custom-message
triggers with their placeholder lists, three worked examples, and the port-clash
warning that produced this week's CAT-drop report.

Amplifiers and Switches: the generic HTTP relay in full — per-relay URLs, the
pattern form, {relay}, {relay-1} and {value} with what each one sends — relay
automatic control with a four-relay antenna-switch example, and the bench power
supply including why OpsLog writes only its output.

Rotators: the two new native types (SPID with the Rot1Prog/Rot2Prog choice,
DCU-1), two-rotor setups, and that Test only reads the heading on the types
where it does.

Awards: the US county database, and the difference between the automatic fill
(blanks only) and the right-click re-derive (replaces) — with the Connecticut
planning regions, which is the case that needs it.

QSL Management: QSL_VIA against QSL_SENT_VIA/QSL_RCVD_VIA, why an import shows E
on every Log4OM record, and that V counts as confirmed.

Troubleshooting: the three field reports of the last few days, by symptom.

+## What follows the active profile
+
+Every setting is per profile, station hardware included. Switching profile
+reconnects the **CAT link**, the **amplifiers**, the **motorized antenna**, the
+**Antenna Genius** and the **tuner** using the new profile's settings — so an
+operator with, say, an SPE on COM9 for HF and another on COM10 for 6 m gets the
+right one by switching profile, with no visit to Settings.
