feat(audit): M5.1 audit tree endpoint + CLI audit tree (T8)
Add GET /api/audit/tree endpoint that accepts executionId query param,
authenticates via HTTP Basic + LDAP (OperationalAudit permission), calls
IAuditLogRepository.GetExecutionTreeAsync, and returns a JSON array of
ExecutionTreeNode. Returns 400 for missing/invalid GUID, 401/403 as normal.
Add `scadabridge audit tree --execution-id <guid> [--format table|json]`
CLI subcommand in AuditCommands.Build(). Adds AuditTreeHelpers with:
- BuildUrl: constructs the relative URL + query string
- RunTreeAsync: calls the endpoint, dispatches to table or JSON renderer
- WriteTable: indented ASCII tree (root → children, [*] marks queried node)
- WriteJson: pretty-printed JSON array pass-through
Tests: 7 new ManagementService endpoint tests (valid id, empty, 400, 401,
403, Viewer allowed, wrong role), 18 new CLI tests (parse, render, HTTP
error codes, JSON output, multi-level indentation, queried-node marker).
