feat(memory-api): add end user management and enhance memory API endpoints

- Add end_user_controller with unauthenticated endpoint for creating end users
- Implement get_or_create_end_user logic to handle duplicate end users by other_id
- Register end_user_controller router in main controller initialization
- Add list_memory_configs endpoint to retrieve all workspace memory configurations
- Update MemoryWriteRequest and MemoryReadRequest to make config_id required field
- Refactor memory API endpoints to parse request body directly instead of using Body parameter
- Add CreateEndUserRequest and CreateEndUserResponse schemas for end user creation
- Add ListConfigsResponse schema for configs listing endpoint
- Remove unused config_id and llm_model_id parameters from Neo4j write operation
- Update .gitignore to exclude redbear-mem-metrics and pitch-deck directories

         Behavior:
-        1. Control branch nodes:
+        1. Force activation:
-           - If `scope` matches a key in `control_nodes` and `status` matches the expected
+           - If `self.force` is True, the method returns immediately.
-             branch label, the End node output becomes globally active (`activate = True`).
+           - If `scope == self.id`, the node marks itself as completed:
+               - `activate = True`
+               - `force = True`
+             This is typically used for final flushing when the node finishes execution.
 
-        2. Variable output segments:
+        2. Control dependency resolution:
-           - For each segment that is a variable (`is_variable=True`):
+           - If `scope` matches a key in `control_nodes`:
-               - If the segment literal references `scope`, mark the segment as active.
+               - `status` must be provided.
-               - This applies both to regular node variables (e.g., "node_id.field")
+               - If `status` matches expected branch labels, mark control as resolved
-                 and special system variables (e.g., "sys.xxx").
+                 (`control_resolved = True`).
+
+        3. Upstream output dependency resolution:
+           - If `scope` is in `upstream_output_nodes`,
+             mark data dependency as resolved (`output_resolved = True`).
+
+        4. Global activation condition:
+           - The node becomes active when BOTH conditions are satisfied:
+               - control_resolved == True
+               - output_resolved == True
+           - Once activated, `activate` remains True.
+
+        5. Variable segment activation:
+           - For each output segment that is a variable (`is_variable=True`):
+               - If the segment depends on the given `scope`,
+                 mark the segment as active.
+           - This applies to both node variables (e.g., "node_id.field")
+             and system variables (e.g., "sys.xxx").

-        - This method does not emit output or advance the streaming cursor.
+        - This method does NOT emit output or advance the streaming cursor.
-        - It only updates activation flags based on upstream events or special variables.
