feat(spot): POTA as a polled spot source (FR-SPOT-08) - #196

Conversation
Read the four networks FR-SPOT-08 names (R-EXT-05) and built POTA. - k4-spot::pota: strict parser for the observed reply (kHz string to Hz, UTC time, park in the comment); a bad record costs only itself, anything that is not a list of flat records is an error shown to the operator. - k4-spot::polled: source for polled networks; the request runs on its own thread so a slow server never delays the other sources; injected fetcher, interval, backoff, hung-request deadline, window and per-reply caps. - app/src/http_fetch.rs: anonymous bounded GET (timeout, size cap, no redirects) on the existing ureq/rustls. - Fourth worker slot, PotaPrefs (off by default, 30 s..1 h, default 60 s), a POTA section in Networks, green nameplates, demo spots. - The worker now rests between passes; with only a polled source it would have spun a core. SOTA, WSPRnet and FreeDV Reporter are not built; each is blocked on a decision or prerequisite recorded in OP-7 (items 5-7).

An earlier note said FreeDV Reporter needs TLS. That was an assumption. SDRoxide's public source (read for interface facts only, per R-EXT-04) connects over plain ws:// in a read-only view role. Also records what it does about POTA (same endpoint), SOTA (a different, unstable host; no credential) and WSPRnet (own callsign only).

…stants The boundary inputs of the POTA parser tests were built from the constants they test (MAX_BODY + 1, MAX_SPOTS + 1), so changing a constant moved the test with it and nothing noticed. Mutating the constants themselves showed MAX_BODY, MAX_SPOTS, the frequency ceiling and the default poll interval all unpinned. The limits are now written as numbers (512 KiB, 2000 spots, 64-character text, 300 GHz plus one hertz, 30 s / 60 s / 1 h). MAX_TOKEN stays an equivalent mutation: the same 64 is applied again downstream by sanitise_text, and a string there is a borrowed slice; documented in the code.
