When running `databricks apps init` with `--set` flags (non-interactive mode), the `.env` file had empty values for PGHOST, PGDATABASE, and LAKEBASE_ENDPOINT. These fields have a `Resolve` property that maps them to values derived from the selected branch. In interactive mode, `PromptForPostgres()` runs the full resolution flow, but in non-interactive mode no resolution logic ran. Extract the resolution logic into a new `ResolvePostgresValues()` function and call it from the non-interactive path after `--set` values are merged. Co-authored-by: Isaac
Extract ResolvePostgresValues from PromptForPostgres to reuse resolution of derived postgres fields (host, databaseName, endpointPath) in the non-interactive/flags code path. Consolidate CollectResources calls. Co-authored-by: Isaac
- Restore RunWithSpinnerCtx in interactive PromptForPostgres for the ResolvePostgresValues call to maintain UX feedback during API calls - Add TestResolvePostgresValuesDatabaseAPIError to cover ListDatabases failure path - Fix comment in init.go to say "derived values" instead of "derived postgres values" since the resolve loop is generic Co-authored-by: Isaac

## Summary
- Extract `ResolvePostgresValues()` from `PromptForPostgres()` so it can
be called from the non-interactive code path
- After `--set` values are merged in flags mode, resolve derived
postgres fields (host, databaseName, endpointPath) by calling
`ListPostgresEndpoints` and `ListPostgresDatabases`
- Fixes empty `PGHOST`, `PGDATABASE`, and `LAKEBASE_ENDPOINT` values in
`.env` when using `databricks apps init` with `--set` flags
## Repro command
Rebuild the CLI and run:
```bash
dbx apps init --name event-registration \
--features lakebase \
--set "lakebase.postgres.branch=projects/4de10316-dd6f-4606-878e-fdf3189f6766/branches/br-divine-term-y10rpplr" \
--set "lakebase.postgres.database=projects/4de10316-dd6f-4606-878e-fdf3189f6766/branches/br-divine-term-y10rpplr/databases/db-5vqi-xormgdrr0m" \
--description "Event registration app with Lakebase" \
--run none --profile DEFAULT --version 0.20.0
```
Then see if .env has filled `PGHOST`, `PGDATABASE`, and
`LAKEBASE_ENDPOINT`:
```
DATABRICKS_CONFIG_PROFILE=DEFAULT
PGDATABASE=databricks_postgres
LAKEBASE_ENDPOINT=projects/4de10316-dd6f-4606-878e-fdf3189f6766/branches/br-divine-term-y10rpplr/endpoints/primary
PGHOST=ep-small-sunset-y12mao90.database.us-west-2.staging.cloud.databricks.com
PGPORT=5432
PGSSLMODE=require
DATABRICKS_APP_PORT=8000
DATABRICKS_APP_NAME=event-registration
FLASK_RUN_HOST=localhost
```
## Test plan
- [x] Existing unit tests pass (`go test ./libs/apps/prompt/...
./cmd/apps/...`)
- [x] Manual test: run the repro command above and verify `.env` has
populated values for `PGHOST`, `PGDATABASE`, `LAKEBASE_ENDPOINT`
- [x] Verify interactive mode still works unchanged
