infra(macmini): bump squeezed container memory limits

Mac Mini was running at 99% memory pressure with 8.6 GB swap active —
load was OK but every cold-container request was paying disk-I/O for
swapped pages. Container observations:

  redis      190/192 MB (99 %)  — close to OOM, hot keys evicting
  victoria   227/256 MB (89 %)  — constant GC pressure
  glitchtip  232/256 MB (91 %)
  umami      223/256 MB (87 %)

Each bumped to 384 MB, total +512 MB reservation in the Colima VM.
Headroom for that comes from stopping the Pelias stack (~3 GB freed)
in the same change-window.

Redis additionally gets `--maxmemory 320mb --maxmemory-policy allkeys-lru`
so the daemon evicts its own LRU keys at ~80 % of mem_limit instead of
letting the kernel OOM-kill the whole container. Safe for our usage —
Redis only holds rate-limit counters + sync hot-paths, no critical state.

Pelias stays stopped pending a migration to mana-gpu; mana-geocoding
will need a Nominatim fallback before the migration so the Places
module's address lookup keeps working.
