* Expose more payload-rule upstream types in Settings
The first payload-rules UI only offered a narrow set of protocol labels, which
made live troubleshooting confusing once real playground traffic routed through
platforms like sub2api instead of codex. This expands the selectable upstream
types, extracts the option list into one small helper, and renames the field to
上游类型 so the UI matches what the runtime matcher actually uses.
Constraint: Must preserve the existing payload-rules schema key (`protocol`) even though the UI wording is now upstream-type oriented
Rejected: Leaving the dropdown codex/openai-only and telling operators to hand-edit JSON | too easy to misconfigure during live routing diagnosis
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If new canonical site platforms are added, update payloadRuleProtocolOptions.ts so the visual editor stays aligned with runtime matching
Tested: npx vitest run --root . src/web/pages/settings.payload-rules.test.tsx src/web/pages/settings.payload-rule-platform-options.test.ts

Not-tested: Manual dropdown interaction in a browser
* Keep payload-rule upstream types aligned with one-api backend support
Code review caught that the visual editor still omitted one-api even though the
backend continues to treat it as a valid upstream platform. This adds the
missing option and extends the focused option-set test so operators can create
payload rules for one-api without dropping to raw JSON.
Constraint: Must preserve the runtime payload-rules schema and only close the UI/backend option gap
Rejected: Removing one-api from the backend in this PR | unrelated behavioral change and broader migration risk
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: When backend platform support changes, update payloadRuleProtocolOptions.ts and its focused test in the same PR

* Make payload request overrides configurable from Settings
The payload-rules engine already existed in the proxy path, but operators had
no supported runtime UI to manage CPA-style overrides. This wires the setting
through the runtime settings API, adds strict validation, and ships a
low-friction visual editor with an advanced JSON fallback so common cases like
Codex high reasoning can be configured without hand-editing backend state.
Constraint: Must reuse the existing payload-rules execution path and settings table without schema changes
Constraint: Must fit the existing metapi Settings-page patterns rather than introducing a standalone config surface
Rejected: JSON-only editor as the primary UX | too long and too easy to misconfigure for common cases
Rejected: A brand-new backend rule format for the UI | would duplicate the existing payload-rules source of truth
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep visual-rule serialization and advanced JSON editing in sync before extending the rule model
Tested: npm run typecheck
Tested: npx vitest run --root . src/server/services/payloadRules.test.ts src/server/routes/api/settings.events.test.ts src/web/pages/settings.payload-rules.test.tsx
Tested: npm run repo:drift-check
Not-tested: Manual browser interaction smoke on the Settings page in this clean PR worktree
* Prevent payload-rules saves from violating review expectations
Code review surfaced two operator-facing edge cases in the first payload-rules
PR: successful rule parsing could still be committed before a later validation
error, and visual edits could silently overwrite unsaved advanced JSON. This
stages payload-rules until the request finishes validating and adds an explicit
confirmation gate before visual actions discard unsynced advanced edits.
Constraint: Keep the fix narrow to the reviewed payload-rules feature without refactoring unrelated runtime-settings atomicity behavior
Rejected: Silently skipping draft resync while keeping visual edits active | would leave save semantics ambiguous when advanced JSON stays dirty
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If the settings endpoint ever moves toward full request atomicity, re-check this staged payload-rules write path against the broader strategy
Tested: npm run typecheck
Tested: npx vitest run --root . src/server/routes/api/settings.events.test.ts src/web/pages/settings.payload-rules.test.tsx
