fix(ci): resolve backend lint F821 and stale frontend test mocks

[anshul23102]

Summary

Fixes two CI regressions introduced by commits 0e03877 and a2a7e02 that are currently blocking all open PRs (backend-lint and frontend-checks failures).

Root Causes

1. Backend lint failure — F821 Undefined name 'db' (backend/secuscan/workflows.py:82)

Commit 0e03877 added a get_target_policy(db, ...) call inside WorkflowScheduler._run_workflow(), but db was never acquired in that method. The tick() method correctly obtains db = await get_db() but does not pass it to _run_workflow().

Fix: Added db = await get_db() at the top of _run_workflow().

# Before
async def _run_workflow(self, workflow_id: str, steps: List[Dict[str, Any]]):
    logger.info(...)
    for step in steps:
        ...
        target_policy = await get_target_policy(db, ...)  # NameError: db undefined

# After
async def _run_workflow(self, workflow_id: str, steps: List[Dict[str, Any]]):
    logger.info(...)
    db = await get_db()  # acquire database connection
    for step in steps:
        ...
        target_policy = await get_target_policy(db, ...)  # now resolved

2. Frontend test failures — stale mocks after ToolConfig.tsx and Workflows.tsx updates

Commit a2a7e02 updated ToolConfig.tsx to call three new API functions in a Promise.all:

const [s, policies, credentials, sessions] = await Promise.all([
  getSettings(),
  listTargetPolicies(),   // new
  listCredentialProfiles(), // new
  listSessionProfiles(),  // new
])

Tests that only mocked the original API functions had these three return undefined, causing Promise.all to resolve with a rejected upstream, which prevented setServerLimits from running and broke max/min attribute assertions in ToolConfigTimeout.test.tsx.

The same commit also updated startTask to accept a 5th executionContext argument, breaking the startTask call assertion in ToolConfigDynamic.test.tsx.

Workflows.tsx changed emptySteps to include execution_context in each step object, making the createWorkflow assertion in Workflows.test.tsx fail with a shape mismatch.

Fixes applied:

File	Change
ToolConfigDynamic.test.tsx	Added listTargetPolicies, listCredentialProfiles, listSessionProfiles, getSettings to vi.mock factory and beforeEach mock returns; updated startTask assertion to accept 5th executionContext argument
ToolConfigTimeout.test.tsx	Added three new API functions to vi.mock factory and beforeEach so Promise.all resolves correctly
Workflows.test.tsx	Updated createWorkflow expectation to include execution_context in the steps array

Verification

• ruff check backend/secuscan/workflows.py passes with no errors
• All three frontend test assertions align with the current component behavior

Impact

This unblocks all currently open PRs that are failing backend-lint and frontend-checks due to these pre-existing regressions.

Focused CI baseline repair with the missing backend db acquisition and updated frontend mocks/resource-list fixtures. Checks are green; approving for merge.
