"""Idempotently seed the Self-Hosted (Ollama) LOCAL provider row.
Revision ID: 028_seed_self_hosted_provider
Revises: 027_system_settings
Create Date: 2026-06-12
The `provider_configs` table already has `type='local'` in the
`modelprovider` enum (seeded in 004_provider_routing). This migration
seeds the corresponding row so the Settings UI can configure a
self-hosted Ollama server without requiring an additional API call.
The row starts disabled with no base_url — the user configures those
via PUT /api/providers/self-hosted. ON CONFLICT DO NOTHING makes this
migration safe to re-run on a DB that already has the row (e.g. from
a prior manual insert or a future fresh-schema bootstrap).
