/**
 * Database Connection Select Component
 *
 * A select component for choosing database connections.
 * Includes inline creation of new connections with connection testing.
 *
 * Data-in / events-out:
 * - Host provides `entries`, `loading`, and `testResult`
 * - Component fires `create-entry` when the user submits the create form
 * - Component fires `test-connection` when the user clicks test
 * - Component fires `value-change` when the selection changes
 *
 * @example
 * ```html
 * <nr-db-connection-select
 *   dbType="postgresql"
 *   .entries=${connectionEntries}
 *   value="postgresql/my-db"
 *   @value-change=${(e) => console.log(e.detail.value)}
 *   @create-entry=${(e) => handleCreate(e.detail)}
 *   @test-connection=${(e) => handleTest(e.detail)}
 * ></nr-db-connection-select>
 * ```
 *
 * @fires value-change - Fired when selection changes
 * @fires create-entry - Fired when user submits the create form
 * @fires test-connection - Fired when user clicks Test Connection
 *
 * @csspart container - The root nr-select wrapper
