## Summary
This pull request focuses on implementing key functionalities needed for network frame processing and database interactions. The primary changes are:
1. **Internal Frame Processing:** The logic has been implemented in various components like `NIC`, `Node`, `SessionManager`, and `SoftwareManager`. These changes enable the system to process incoming and outgoing network frames in a structured manner.
2. **Database Service and Client:** The `DatabaseService` simulates a SQL database server, while the `DatabaseClient` provides a client interface for connecting to this service. These functionalities have been built and integrated into the existing architecture.
3. **Networking and Communication:** Tests have been added to confirm that database queries can be sent over the network, demonstrating end-to-end functionality.
## Commits
- #1816 Simplified a bunch of stuff in the file system in prep for services and applications. Started adding the database logic. Waiting for the software manager/session manager work from another tick. Merge branch 'dev' into feature/1816_Database-Service-(Network-and-User-Interaction)
- #1816 Added the final pieces of the puzzle to get data up from NIC → session manager → software manager → service.
- #1816 DatabaseService now uses the send function when responding.
- #1816 Added database client. Installed the database client on the Web Server node in the UC2 network. Updated the integration test to query the DB server using the DB client.
- #1816 Added full documentation on the database client/server, and the internal frame processing process
- #1816 Fixed tests. Used node and link added number (id) in observation space.
## Test process
For testing these functionalities, the following steps were taken:
1. **Unit Tests:** Tests have been written to confirm that database queries can be sent over the network successfully.
2. **Integration Tests:** Manually tested the frame processing flow from NIC to Service/Application, ensuring the functionality behaves as expected.
3. **Database Queries** Executed sample SQL queries using the `DatabaseClient` to make sure it interacts correctly with the `DatabaseService`.

## Summary
In this pull request, we've made several key enhancements and fixes to improve the routing and network simulation functionalities of our codebase. At the heart of this PR is the introduction of a `Router` class, complete with `ACLRule` and `RouteTableEntry` classes to facilitate easier management of routes and permissions. We've also fixed a lingering issue with the `.ping` functionality, ensuring that it properly checks for replies before returning a boolean value.
To make our `Router` class more inspectable, `.show()` methods have been added which can output information in both plain text and markdown formats. Additionally, we've removed the `gateway` field from the `NIC` class and relocated it to the `Node` class. This move allows each `Node` to have a single default gateway. To further refine the system, we've added `Computer` and `Server` classes, and updated our restructured text formatted docstrings and documentation. Finally, a UC2 network has been added.
Changes have been fully tested to ensure that the existing functionalities remain intact, and new unit tests have been added to verify routing between different subnets. The code has been synced with the dev branch.
## Test process
We've added new unit tests and integration tests to check the routing capabilities when a router is placed between different subnets. These tests specifically focus on the ping functionality to verify that it works as expected after the changes. Existing tests were also run to make sure no existing functionality was broken.

- Added .show() methods to new router classes to enable inspection of the components as you would a real router.
- Removed gateway from the NIC and added default_gateway to Node so that Node has a single default gateway.
- Added some routing tests to check that ping can be performed when router between subnets.
