🧱 fix: Enforce Agent Access Control on Context and OCR File Loading (#12253)
* 🔏 fix: Apply agent access control filtering to context/OCR resource loading

The context/OCR file path in primeResources fetched files by file_id
without applying filterFilesByAgentAccess, unlike the file_search and
execute_code paths. Add filterFiles dependency injection to primeResources
and invoke it after getFiles to enforce consistent access control.

* fix: Wire filterFilesByAgentAccess into all agent initialization callers

Pass the filterFilesByAgentAccess function from the JS layer into the TS
initializeAgent → primeResources chain via dependency injection, covering
primary, handoff, added-convo, and memory agent init paths.

* test: Add access control filtering tests for primeResources

Cover filterFiles invocation with context/OCR files, verify filtering
rejects inaccessible files, and confirm graceful fallback when filterFiles,
userId, or agentId are absent.

* fix: Guard filterFilesByAgentAccess against ephemeral agent IDs

Ephemeral agents have no DB document, so getAgent returns null and the
access map defaults to all-false, silently blocking all non-owned files.
Short-circuit with isEphemeralAgentId to preserve the pass-through
behavior for inline-built agents (memory, tool agents).

* fix: Clean up resources.ts and JS caller import order

Remove redundant optional chain on req.user.role inside user-guarded
block, update primeResources JSDoc with filterFiles and agentId params,
and reorder JS imports to longest-to-shortest per project conventions.

* test: Strengthen OCR assertion and add filterFiles error-path test

Use toHaveBeenCalledWith for the OCR filtering test to verify exact
arguments after the OCR→context merge step. Add test for filterFiles
rejection to verify graceful degradation (logs error, returns original
tool_resources).

* fix: Correct import order in addedConvo.js and initialize.js

Sort by total line length descending: loadAddedAgent (91) before
filterFilesByAgentAccess (84), loadAgentTools (91) before
filterFilesByAgentAccess (84).

* test: Add unit tests for filterFilesByAgentAccess and hasAccessToFilesViaAgent

Cover every branch in permissions.js: ephemeral agent guard, missing
userId/agentId/files early returns, all-owned short-circuit, mixed
owned + non-owned with VIEW/no-VIEW, agent-not-found fail-closed,
author path scoped to attached files, EDIT gate on delete, DB error
fail-closed, and agent with no tool_resources.

* test: Cover file.user undefined/null in permissions spec

Files with no user field fall into the non-owned path and get run
through hasAccessToFilesViaAgent. Add two cases: attached file with
no user field is returned, unattached file with no user field is
excluded.
