chore(api): remove unused and superseded API routes

[waleedlatif1]

Summary

• Remove the manually rolled email template preview route (/api/emails/preview) and its schema
• Remove legacy copilot chat routes superseded by the /api/mothership/* surface: chat/rename, chat/update-messages, chat/steer, checkpoints, checkpoints/revert, credentials, models, and mothership/local-files/stage
• Remove table transfer routes superseded by the imports/exports resource flow: export-async, export/download, import-async (both table-level and per-table), job/cancel
• Remove routes with no remaining callers: billing/credits, files/download, logs/triggers, workspaces/[id]/metrics/executions, status, organizations/[id]/invitations, workspaces/[id]/files/[fileId]/compiled-check (compiled checks now run in-process via the VFS)
• Remove tools/cloudwatch/describe-log-* HTTP routes superseded by shared selectors and in-process tool execution (contracts kept for the in-process executor)
• Clean up all orphaned contracts, schemas, use cases, error policies, and tests; retarget the executor-capability test to the live import-csv route

Type of Change

• Chore

Testing

Full test suite passes (2851 files / 39297 tests), bun run type-check, bun run lint, and all 44 check:audits pass. Verified no external callers for every removed route across sibling service repos; routes with external consumers were kept.

Greptile Summary

This PR removes obsolete API endpoints and their now-unused contracts, helpers, error projections, and tests after the relevant behavior moved to newer resource and Mothership surfaces.

• Removes legacy Copilot, table-transfer, billing, file, logs, status, metrics, invitation, and CloudWatch HTTP routes.
• Deletes orphaned schemas and implementation helpers associated exclusively with those routes.
• Retargets the table executor-capability test to the live CSV import endpoint.
• Updates API-validation baselines and lockfile metadata to match the resulting tree.

Confidence Score: 5/5

The PR appears safe to merge; no changed-code-triggered blocking or independently actionable non-blocking issue was identified.

The removed routes, contracts, helpers, and tests have no remaining repository references, the retained replacement surfaces cover the updated test path, and the lockfile change does not modify dependencies.

Important Files Changed

Filename	Overview
apps/sim/lib/api/contracts/copilot.ts	Removes contracts and schemas belonging exclusively to the deleted legacy Copilot endpoints without leaving head-tree references.
apps/sim/lib/api/contracts/tables.ts	Removes contracts for superseded asynchronous table-transfer endpoints alongside their route implementations.
apps/sim/lib/copilot/chat/messages-store.ts	Removes the full-snapshot replacement helper whose sole consumer was the deleted update-messages route.
apps/sim/lib/billing/credits/purchase.ts	Removes the unused direct credit-purchase implementation while retaining the live usage-limit reconciliation helper.
apps/sim/app/api/table/executor-capability-exemption.test.ts	Retargets executor-versus-session permission behavior coverage from the removed async import route to the live multipart CSV import route.
scripts/check-api-validation-contracts.ts	Cleans obsolete route entries from the raw-JSON audit baseline; no behavioral regression was identified.
bun.lock	Adds only Bun lockfile-format metadata and does not alter package versions or dependency resolution.
