perf(proxy): stagger scheduled background jobs across jobs and pods (#36589)
APScheduler anchors an interval job at now + interval, so every scheduled
background job registered in one proxy startup shares a single firing instant
for the life of the process, and every replica a rollout brought up together
shares that instant too. Each tick the spend flushes, budget reset sweep,
config-in-DB reload, credential reload and cost pollers all hit Postgres at the
same moment, on every pod, competing with request-path auth and budget queries.

Shift each eligible job by a deterministic offset derived from
sha256(job_id, identity), where identity covers the pod and the worker process.
The offset lives in the trigger rather than in a one-off next_run_time, because
a cron trigger recomputes each fire from the wall clock and would otherwise snap
straight back onto the shared instant. An interval job is never offset by more
than one of its own periods.

Only schedules LiteLLM chose are shifted: interval jobs always, cron jobs only
when the id is one of the product's own defaults, so an operator-supplied
crontab keeps the instant it asks for. general_settings.scheduled_job_stagger
turns it off, widens the window, replaces the identity, or pins a job. The
applied offsets are logged once at startup and each fire logs its scheduled
instant against its actual start.
