Brisbanehuangandshaw fad2f215e8 fix(profit-control): decouple gate from image intent, propagate gate via selection, restore eager sticky fallback
Review fixes for the profit-control feature commit:

- Image intent no longer disables the profit gate. The shared /v1/responses
  handler previously skipped the pricing context (and therefore the gate)
  whenever the platform-wide image intent predicate matched, which includes
  Codex's passive image_gen namespace declaration: any client could disable
  admission control for anthropic/gemini/antigravity groups by declaring a
  namespace tool in the request body. Both /v1/responses paths now always
  install the token pricing context; image intent only drives capability
  routing and image billing. Mixed token+image requests stay token-gated;
  only dedicated media endpoints remain out of scope.
- Out-of-scope paths are now explicitly suppressed instead of implicitly
  ungated: Grok media (billed by media multipliers; also prevents in-flight
  video lookups from turning into spurious 404s), OpenAI-group count_tokens
  (unbilled), and Live calls (duration billed) carry a suppress marker that
  every install point honors, including the defensive scheduler-entry
  install.
- The gate resolved during selection now travels back to handlers on the
  AccountSelectionResult. The shared gateway installed the gate only on a
  scheduler-local context, so handler-side post-slot terminal rechecks and
  post-admission sticky binding were no-ops for anthropic/gemini/
  antigravity/shared-grok requests (and for composite-routed member groups
  on the OpenAI path). Handlers re-apply the carried gate via
  ContextWithSelectionProfitGate before the terminal recheck and binding;
  the WS acquired-selection branch gained the previously missing recheck.
- Sticky binding semantics restored for ungated traffic:
  BindStickySessionAfterProfitAdmission falls back to the official eager
  bind when no gate is installed (wait paths lost their only binding point
  otherwise), reads the pre-existing binding at bind time only when gated
  (removes the unconditional per-request Redis read the feature added to
  the shared handlers), and the legacy engine's three selection-time
  binding writes are skipped under a gate so a terminally vetoed account
  can no longer become the new sticky target.
- Responses WS connections re-freeze pricingAt and re-resolve the gate at
  every turn (BeforeTurn) and bill each turn with its own instant, closing
  the connect-at-valley/bill-at-valley window; a turn that fails the
  recheck closes the connection so the client reselects on reconnect.
- Terminal recheck no longer swaps a DB-fresh selected account for a
  staler snapshot object (UpdatedAt guard), and observer counters are
  documented as per-evaluation.
- Migrations renumbered 191/192 -> 192/193 after the passkey migration
  landed upstream as 191.

New regressions: selection-carried gate propagation (control group proves
the pre-fix no-op), image intent not disabling the shared gate, eager
binding fallback without a gate (both services), gated
read-failure/sentinel-miss binding semantics, legacy-engine deferred
binding under a gate with eager behavior preserved ungated, turn-level
pricing refresh (config re-resolution, scheduled-group precedence,
suppress, mid-connection disable), and suppress-marker coverage for the
request pricing context.
