Refactor Agent Tool Assignments to Database-Driven Static Loading (#45)

* Refactor tool loading to use static database assignment

- Add `tools` field to `WorkerIndividual` and `SystemNodeConfig` models
- Update frontend WorkerIndividualSettings to support multi-select tools and select `bound_skill` from available backend API
- Deprecate dynamic `get_tool` method during agent execution, replacing it with `load_tools_from_list` via absolute paths during agent initialization
- Fix deprecated tool loading usage across `SupervisoryNode`, `ConsciousnessNode`, `ControlNode`, and `BaseIndividual`
- Provide `reload` API route to clear `GlobalIndividualManager` state to rebuild nodes cleanly upon next request
- Fix `user_test.py` related to unhashed password assignments in testing mock object

* Refactor tool loading to use static database assignment part 2

- Restore BaseIndividual's `_init_agent` method to inject parsed `tools_list` via absolute paths dynamically using `load_tools_from_list`
- Restore React component multi-select support for tools dropdown via `/api/v1/resource/tool` backend response integration
- Restore `user_test.py` compatibility related to access hasher assignments
- Passed 75 tests with no errors

* Finalize all tool loading refactoring with complete changes

- Merged database schema enhancements for `tools` multi-select list
- Completed the `load_tools_from_list` via absolute paths utility update
- Refactored `AgentFactory` and corresponding initialization calls in `BaseIndividual`, `SupervisoryNode`, `ConsciousnessNode`, and `ControlNode` to inject statically via constructor
- Updated frontend UI `WorkerIndividualSettings` with UI for `bound_skill` selection and dynamic multi-tool selector array
- Removed all legacy usages of dynamic `tools=tool` invocation
- Provided backend `/reload` API and automatic clearing of instance cache upon individual configuration update
- Repaired mock password assignment logic in testing suite

* Restore complete tool loading refactor logic

- Re-apply BaseIndividual tools resolution logic
- Correctly patch API, UI files, system nodes and testing scripts avoiding checkout loss
- Passed all 75 integration and unit tests successfully
