ZdenekSrotyr 103efb69f0 chore(cli-rename): replace stale da verbs in active code paths
Bring admin UI, audit-log messages, code comments, and analyst-facing
skill docs in line with the post-bootstrap CLI surface (`agnes pull`,
`agnes push`, `agnes init`, `agnes snapshot create`). The legacy
`_LEGACY_STRINGS` detection tuple in `app/api/claude_md.py` and the hook
upgrade markers in `cli/lib/hooks.py` are intentionally left as-is —
they exist precisely to flag pre-rewrite content for re-authoring.

Strip "(folded from `da metrics list`)" / "(lifted from `da metrics
show`)" / "Replaces the old `da analyst status`" docstring noise — the
rename history is in CHANGELOG.md, not in module docstrings.

"""Shared CLI renderer for HTTP error responses.
Three CLI paths surface BigQuery / guardrail / RBAC typed errors today:
- ``agnes query --remote`` (POST /api/query)
- ``agnes query --register-bq`` (RemoteQueryEngine wrapping BqAccessError)
- ``agnes snapshot create`` / ``agnes schema`` etc. (cli.v2_client wrappers around v2 endpoints)
All three previously flattened the structured ``detail`` JSON to a
truncated single-line string, hiding the operator-facing hint that
explains how to fix ``USER_PROJECT_DENIED`` / cost-cap rejection /
unregistered ``bq.*`` paths. This module recognizes a few canonical
shapes and pretty-prints them; falls back to truncated form for
anything unrecognized so the renderer never makes a worse-than-
status-quo error message.
Closes #160 §4.7.
