cproudlock 75627d4398 Close the review findings on the policy routes, installer and import
Applied on top of af13337 so nothing already on wilm is rewritten.

AUTHORIZATION. The six new policy GETs were @jwt_required(optional=True) with
no permission at all, so an anonymous caller could list configuration and
business policies - gated only by a feature flag that 404s while off. They now
require computers.view. The six policy write routes stacked @jwt_required()
above @require_permission, the same pattern removed from nine endpoints routes
in this very push: the outer decorator answers an anonymous request 401 before
require_permission can consult the guest role, so a grant to guests silently
does nothing. Removed, and the now-unused import with them.

tests/test_core/test_public_read_surface.py failed at af13337 with seven ungated
GETs. It passes now. The seventh, endpoints.claim_next_command, is genuinely
agent-facing - authenticated in the handler by the endpoints collector key,
because a bay has no user session - so it joins PUBLIC_ENDPOINTS with its reason
written down, exactly as report_command_result already does in test_authz.py.
Note which half is public: claiming a queued command is the agent's business,
while ENQUEUEING one is the real authority and stays gated on endpoints.command.

INSTALLER. -BaseUrl and -CollectorKey are now mandatory with no defaults, and
https is enforced unless -AllowInsecureHttp is passed for a local test box. The
defaults were a real hostname (ADR-015) and a live collector key: a key in
source is a key in git history, and that key is also the command channel's kill
switch. Removing it here does not undo the disclosure - it must be rotated on
the server, and purged from af13337 - but it stops the next clone carrying it.

IMPORT. A committed import wrote thousands of rows and left no audit trail; it
now writes one AuditLog row inside the same transaction, so it cannot survive a
rollback or go missing from a commit. The computer-type dropdown asked for
per_page: 200, which the API ignores in favour of perpage and clamps to 100
anyway - it uses a new computersApi.types.listAll(), the pattern already applied
to the other selectors. And the comment claiming the template example rows are
"emitted as commented rows the engine skips" was the opposite of the truth: they
import as live data, the emitted instructions say so, and a test depends on it.

Not fixed here, deliberately: rotating the leaked key, purging it from history,
and the endpoint agent's own hardening (per-host credentials, a protected
process denylist so stop cannot kill security tooling, signing before the
PowerShell runner is enabled, registry ACLs, and the 25-second long poll that
will pin a worker thread per bay).

"""CRUD API for Configuration and Business Policies.
Registered on computers_bp under /api/computers/policies/... Kept in its own
module so the whole policy surface can be removed by not importing it - part of
the exit gate. Every route first checks the computers_configpolicies_enabled
switch and returns 404 while it is off, so enabling/disabling the feature never
half-exposes it.
Write-time validation lives here (not in the model): scope ASTs go through
validate_scope, and action names are checked against the endpoints command
allowlist, so a bad tree or an unknown action never reaches the database.
