feat(pm-wizard): drive mutation auth from provider metadata

[aaight]

Summary

Implements metadata-driven auth for PM wizard mutation helpers.

Card: https://trello.com/c/6a004e0e420dd9f9ea6a32f9

Changes

• Pass the active provider wizard id and auth metadata through ProviderHooksContext so provider hook modules no longer hard-code their own mutation auth metadata.
• Add metadata-driven request builders for provider label creation and custom-field creation, both using buildProviderAuthArgFromMetadata.
• Update Trello, Linear, and JIRA provider hook wiring to receive provider ID/auth from the manifest context.
• Extend pm-wizard-hooks unit coverage for raw credential payloads, stored credential { projectId } fallback, and missing-credential errors across Trello, JIRA, and Linear mutation flows.

Verification

• npx vitest run --project unit-core tests/unit/web/pm-wizard-hooks.test.ts
• npm run lint:fix
• npm run lint (passes with existing warnings)
• npm run typecheck
• npm test
• npm run test:integration

Notes

npm run lint still reports existing warning-level findings in unrelated files; it exits successfully with no errors.

LGTM - the mutation request builders now use manifest auth metadata, provider hooks receive the active manifest id/auth from context, and the targeted pm-wizard-hooks unit suite passes locally.
