Oliver Kieselbach bcd307d8a4 perf(backend): project index scans + bound AppInstall reads to window ...

Two classes of read-efficiency fixes on hot/aggregation paths. No response
shape or value changes — DTOs untouched, all 2541 backend tests pass.

P2 — select projections on full-mirror SessionsIndex scans (bandwidth only):
- GetMetricsSummaryAsync: cross-partition status tally now projects
  [PartitionKey, Status] instead of the ~40-column mirror row (incl. the
  large FailureSnapshotJson) -> ~10-20x less transfer.
- QuickSearchSessionsAsync: typeahead scan projects only the matched fields
  (+ RowKey for the SessionId fallback) instead of the full row, for up to
  QuickSearchMaxScannedRows rows per request.

P3 — push the existing sinceUtc window floor server-side at 8 AppInstall
call sites across 5 files (previously each dematerialized the whole table /
partition and filtered to the window in memory):
- UsageMetricsService (global + tenant): now.AddDays(-days)
- MaintenanceService.Aggregation (global + tenant, per aggregated day): targetDate
- SlaBreachEvaluationService (current ISO week): now.AddDays(-8) margin
- SlaMetricsService: startDate (matches the in-memory lower bound exactly)
- Get(Global)GeographicLocationSessionsFunction: cutoff

Each floor equals the session-window floor the apps are joined against
(app.StartedAt >= session.StartedAt >= floor), so results are unchanged.
