Kagura eefc6cebaa feat(server): add workspace-level always_redact_env setting (MUL-2495) (#2367)
* feat(server): add workspace-level always_redact_env setting

When a workspace opts into always_redact_env (via workspace settings JSON),
all agent GET/LIST responses will have custom_env values masked and
mcp_config nulled regardless of the caller's role. This provides a stricter
security posture for single-tenant self-hosts or environments where
screen-sharing or pairing makes plaintext secrets a risk.

The setting is opt-in and defaults to false (preserving existing behavior).
Owners can still write secrets via the update path; they just cannot read
them back through the API when this setting is enabled.

Closes #2352

* fix(server): fail-closed on GetWorkspace, add HTTP tests, distinguish redaction reason

Address review feedback on #2367:

1. GetWorkspace failure now returns 500 instead of silently defaulting
   to alwaysRedact=false (fail-open → fail-closed).

2. Add HTTP-level regression tests for always_redact_env:
   - GetAgent with flag on → owner sees redacted env
   - ListAgents with flag on → owner sees redacted env
   - GetAgent with default settings → owner sees plaintext env

3. Add custom_env_redacted_reason field ('policy' | 'role') to
   distinguish workspace-policy redaction from role-based redaction.
   UI now only sets readOnly when reason is 'role', allowing owners
   to edit env even when always_redact_env is enabled.

4. Write-back footgun tracked in #2999.

* fix(test): clear workspace settings before DefaultNoRedactForOwner

Guard against test-order leakage: if a preceding test enabled
always_redact_env on the shared workspace and its cleanup didn't
run (e.g. due to -shuffle or parallel execution), this test would
incorrectly see policy-level redaction. Explicitly reset settings
to NULL before assertions.

* fix(ui): make EnvTab read-only when env is redacted by any policy

Previously the readOnly guard only checked for 'role' redaction,
leaving the tab editable under 'policy' redaction. This meant
a user could save the form with '****' placeholder values,
permanently overwriting the actual secrets.

Use the boolean custom_env_redacted flag instead so the tab is
locked regardless of the redaction reason.

Fixes the regression flagged in the third-pass review.
