fix: OpenCode live provider import updates (#4712)

* fix: sync existing opencode providers from live config

* fix: preserve OpenCode provider display names

* docs: update comments and log messages to reflect new update behavior

- fix stale comment in lib.rs that said existing providers are skipped
- change log message from 'Imported' to 'Synced' since count now
  includes both new imports and updates
