fix: resolve OpenAPI 500 error caused by BigInt serialization in stopGracePeriodSwarm

Change Drizzle column mode from "bigint" to "number" for stopGracePeriodSwarm
across all 6 service schemas. This fixes JSON.stringify failing silently in the
@dokploy/trpc-openapi adapter, which unlike the tRPC endpoint does not use
superjson and cannot serialize BigInt values.

No database migration needed — only the JS representation changes. The values
are nanosecond grace periods that fit safely within Number.MAX_SAFE_INTEGER.

Also adds onError logging and export const config to the OpenAPI route handler
to match the tRPC route and improve debuggability.

Fixes #3793
