[AZ-492] Cycle 3 batch 4: perf harness PT-07 + PT-08 + JWT-attach

Drains all three deferred perf-harness items in one batch:
- PT-01..PT-06 now carry Authorization: Bearer minted via the canonical
  SatelliteProvider.TestSupport.JwtTokenFactory (AZ-491) — no third copy
  of JWT logic in the shell.
- PT-07 implemented as cold + warm dual-pass distribution (N=20 each),
  reports p50/p95 for both passes and fails if warm p95 >= cold p95.
- PT-08 implemented as 20-batch upload distribution with batch p95 gated
  at the AZ-488 2000 ms target; per-item gate cost reported as derived
  proxy (batch_p95 / batch_size).

New SatelliteProvider.IntegrationTests/PerfBootstrap.cs adds two CLI
short-circuit subcommands (--mint-only and --gen-uav-fixture <path>)
invoked by the shell so the perf script never inlines the JWT or
JPEG-fixture logic. The dispatch sits at the top of Program.cs Main
and runs before any HTTP / DB / readiness setup.

performance-tests.md PT-07 + PT-08 flip from Deferred to Implemented.
traceability-matrix.md PT-07 + PT-08 rows move from recorded to covered
(PT-08 partial due to per-item proxy — flagged Low in batch-4 review).
_docs/_process_leftovers/2026-05-11_perf-pt07-harness.md deleted; the
leftovers directory is now empty.

Closes cycle-2 retro Action 2; LESSONS.md [process] rule about Deferred
NFRs remains in force as a guardrail.

Also includes the previously-uncommitted cumulative review report for
cycle-3 batches 01-03 (generated at the end of batch 3 but not staged).
