Oliver Kieselbach 27ef527e80 fix(backend): server-bound retention fanout read to per-run cap
The retention fanout materialized the entire eligible-session backlog every
run (GetSessionsOlderThanAsync returned a full List<SessionSummary>) but only
advanced MaxEnqueuesPerTenantPerRun=100 per tenant. A large backlog was reread
and rematerialized each run, so maintenance got slower as the backlog grew
while only 100 sessions progressed.

Cap the read at the per-run dispatch limit: GetSessionsOlderThanAsync gains a
maxResults parameter that caps maxPerPage and stops enumerating once the cap is
reached. The fanout fetches MaxEnqueuesPerTenantPerRun+1 (the +1 is a cheap
"more remaining" probe) instead of the whole backlog. Read cost is now
proportional to the cap, not the backlog; per-run progress is unchanged.

The exact eligible count is no longer known without a full scan, so the audit
now records EligibleThisRun + a MoreRemaining flag instead of the exact total.
