Add generic principal audit context to pending actions

[chubes4]

Summary

• Adds generic, redacted tool execution audit context with principal class, credential scope, source summary, timestamp, and result status.
• Carries that audit metadata into staged pending actions and exposes frontend-ready pending-action list/get rows with flattened fields and resolve hints.
• Normalizes CLI pending-action rows so action kinds like bundle_upgrade can list without requiring legacy top-level agent_id fields.

Closes #2563.
Refs #2564.
Refs #2526.

Verification

Notes

• vendor/bin/phpcs <edited files> is not currently usable as a targeted signal without a repo config; it flags existing project tab indentation/docblock style across unchanged lines.
