Resolve PI Web API pipeline tags through the tag database
- Load active `pi_web_api` connectors and referenced tags behind the
`connectors-pi-web-api` patch, so replays of older runs are unaffected.
- Resolve `pi_web_api_scouter` read tags and `predictions_batch` output
tags by `tag_id`; legacy `webid` pipelines produce identical input.
- Add a `connection` block to scouter schedules with the secret reference
only, plus connector defaults for period, max_count and api_timeout.
- Hold pipelines whose tags span several connectors and notify unresolved
tags, wrong categories and missing connectors once per run.
- Share the issue notification logic between slots and schedules.
