ℹ️ Issue

Closes #10

📝 Description

Added the retrieval methods needed for tags to be looked up by ID or category.

Briefly list the changes made to the code:

1. Added an endpoint to retrieve a single tag by ID.
2. Added an endpoint to retrieve multiple tags from a list of IDs.
3. Added an endpoint to retrieve tags by category.
4. Added validation for missing tag IDs and invalid categories.
5. Added unit tests for successful retrievals, missing IDs, invalid categories, and empty ID lists.
6. Added inline documentation for the new controller and service methods.

✔️ Verification

What steps did you take to verify your changes work? These should be clear enough for someone to be able to clone the branch and follow the steps themselves.

Wrote and ran unit tests. Manually tested endpoints using Postman.

We can delete tag.entity.ts, I probablt left that there by accident. I'll handle that

Thank you for your hard work on this and finding that bug with the API testing! I totally missed it that bug so I appreciate you finding that.

I've requested minor changes, but some of the surface level API testing I've done may have revealed bugs. If you could review them and then re-request me as a reviewer, that would be great, thank you!

[SamNie2027]

Okay I think when I did the categories one I did that API test totally wrong, that's totally my bad

The findById endpoint needs to be a GET endpoint, not a POST endpoint

[SamNie2027]

Thank you for addressing all of the feedback so quickly! I just have one request that I missed in my first review - the getTagsByIds is supposed to be a GET endpoint since the purpose of the endpoint is for retrieving data which is why my API test for that didn't succeed, since I was testing it as a GET endpoint.

Resolve the Type errors and then I think you should be good, thank you!
Disregard this I am on the wrong PR.
