feat: clicking the status-bar amplifier chip toggles OPERATE <-> STANDBY (SPE/ACOM, optimistic flip reconciled by the poll; disabled offline) — PGXL still opens Settings, it has no standby command

The station-control code rebuilt a fresh driver on every status poll and every
relay set. Stateful boards (Denkovi FTDI D2XX, USB-serial) hold an OS handle only
one opener can own, so the first poll opened the board and leaked the handle, and
every poll after failed with 'device in use' — the relays greyed out a second
after Save and auto-control never switched. Drivers are now cached per device and
reused, closed on config change. Adds a Test-connection button + detect feedback
in the device editor (reported by VK4MA).

+// Package acom drives the ACOM solid-state amplifiers (500S / 600S / 700S /
+// 1200S / 2020S) over their (unpublished) RS-232 protocol, reverse-engineered by
+// the ACOM-Controller project (bjornekelund, C#). The amp is reached either
+// directly over a serial COM port (9600 8N1) or over TCP via an RS232-to-Ethernet
+// bridge — both are just an io.ReadWriteCloser to this code, same as the SPE
+// backend.
+//
+// Wire format (host → amp): fixed raw byte strings, validated by the same rule as
+// telemetry (sum of ALL frame bytes ≡ 0 mod 256):
+//
+//	enable telemetry:  55 92 04 15
+//	disable telemetry: 55 91 04 16
+//	OPERATE:           55 81 08 02 00 06 00 1A
+//	STANDBY:           55 81 08 02 00 05 00 1B
+//	OFF (power down):  55 81 08 02 00 0A 00 16
+//
+// Power ON is NOT a data command: it is a hardware pulse on the serial DTR/RTS
+// lines (the amp's remote power-on pins) — serial transport only, and only if the
+// cable wires those pins (a telemetry-only cable uses just RX/TX/GND).
+//
+// IMPORTANT: DTR and RTS must be held LOW at all times otherwise — asserting them
+// permanently blocks the amplifier's front-panel power button.
+//
+// Telemetry (amp → host): once enabled, the amp streams 72-byte frames starting
+// 0x55 0x2F, valid when the sum of all 72 bytes ≡ 0 (mod 256). Field offsets are
+// decoded in decodeFrame below.
