Set up mix_gleam archive, gleam_stdlib, and gleeunit deps. Add Gleam
compiler to all Dockerfiles, CI workflows, nix shell, and .tool-versions.
Rewrite Numeric, QueryHelpers, and URLValidator from Elixir to Gleam with
full ExUnit test coverage. Update all callers to use the Gleam modules
directly via :towerops@module syntax. Remove duplicate sanitize_like/1
private functions in snmp.ex and trace.ex.

Every timeout stack trace pointed at ssl_gen_statem.call/2 — the OTP 27
SSL gen_statem hanging during recv. PG is on private network (10.0.15.20)
and SSL verify was already disabled (verify_none), providing no security
benefit while adding CPU overhead and the gen_statem layer that caused
all connection timeouts.
Removed DATABASE_SSL and DATABASE_SSL_VERIFY env vars from both the
init container and main container. Also disabled SSL on the PG server
(ssl=off in postgresql.conf, hostssl→host in pg_hba.conf).

Pods were running at 500m/500m (100% of limit) with 44-47% of scheduling
periods being CPU-throttled. SSL decryption is CPU-intensive — when the
BEAM gets throttled mid ssl_gen_statem:call/2, the SSL recv stalls until
the cgroup allows CPU again, causing the 15s DBConnection timeout.
This was the actual root cause of "client timed out because it queued
and checked out the connection for longer than 15000ms" errors. Previous
fixes (TCP keepalive, pool tuning, oban pruner) were treating symptoms.
- CPU limit: 500m → 2000m (4 cores burst capacity)
- CPU request: 100m → 500m (guarantee adequate baseline)
