docker compose config --images daemon does not filter to the named service
on this host's Compose v5.3.1 -- it prints every service's image, one per
line, in file order, so `| head -1` was silently grabbing db's image
(timescaledb) instead of daemon's. The probe then always found no
/usr/local/bin/thermograph-daemon in a Postgres image and dropped daemon
from every backend deploy, regardless of what the real backend image
contained.

Fixed by building the image reference directly from the same vars
docker-compose.yml's daemon.image: already interpolates, instead of going
through docker compose config at all.

Reproduced against beta directly: the old sequence selected the wrong
image; the new construction resolves correctly and the binary probe
passes.

MonthPage and RecordsPage each made two backend calls sequentially
(CityMonth/CityRecords, then City) where the second never depended on the
first's result. fetchWithCity launches both concurrently via goroutines
and a WaitGroup.

Verified live against a stub with an injected 400ms delay on both
endpoints: city page (1 call) and month/records pages (2 calls each) all
cost ~0.404s now, not double for the two-call pages.

Error priority preserved exactly: primary's error wins even when City
also fails, matching the old sequential code. One trade-off: City() is
now always launched even on a request about to 404 from primary, costing
one extra cheap lookup on that rare path.

Tests include a deterministic concurrency proof via rendezvous channels
(the old sequential code would deadlock this test, not just run it
slower). Full suite green under -race -count=2.
