A Prisma migration for the FeePayer model is required.

The FeePayer model was added to schema.prisma but no corresponding migration exists. The services actively query this table: fee-payer.service.ts calls prisma.feePayer.findFirst(), prisma.feePayer.update(), and prisma.feePayer.findMany(), while rebalancing.service.ts also calls prisma.feePayer.findMany().

Without the migration, these queries will fail at runtime with a "table does not exist" error, breaking fee payer selection and rebalancing logic.

Generate the migration with npx prisma migrate dev --name add_fee_payer and ensure it's applied before deployment.

Verify each finding against the current code and only fix it if needed.

In `@server/prisma/schema.prisma` around lines 306 - 317, Add and apply a Prisma
migration for the new FeePayer model so the DB table exists before services
query it: run the migration command (npx prisma migrate dev --name
add_fee_payer) to generate the migration for the FeePayer model (fields: id,
publicKey, isPaused, lastUsedAt, balance, createdAt, updatedAt and indexes on
isPaused and lastUsedAt), confirm the migration is applied to your environment,
and include the generated migration in the repo/CI so calls from
fee-payer.service.ts (prisma.feePayer.findFirst, update, findMany) and
rebalancing.service.ts (prisma.feePayer.findMany) will not fail at runtime.
