[Feature] Add APIs for fetching role information

[bksh05]

Issue

There was no API to get the role_id of roles in the server and role_ids were hard coded.

Description (fixes #79 )

This PR adds the below APIs 1: GET /roles: Fetches all role IDs and names. 2: GET /roles/:roleName: Retrieves role details (role_id and role_name) based on the provided role name.

These changes improve the system's ability to handle role-related operations and enhance the overall role-management experience.

Anything you would like to inform the reviewer about:

@RitikJaiswal75 Last time I added a coverage report, you asked to show if the code that I wrote is covered or not 😂. Hence, this time I attached the code showing that whatever I wrote in this PR is 100% covered by test cases.

I would really appreciate it if we have a consensus on what is expected to attach in the PR 🤝. Though I am adding what I get after running npm test.

Note: My functions/methods/controllers are covered 100%. There are other functions in the same file whose test cases are not written at all. Hence the coverage is low. We can ask the respective developer to add those or create a separate issue for it.

@RitikJaiswal75 Last time I added a coverage report, you asked to show if the code that I wrote is covered or not joy. Hence, this time I attached the code showing that whatever I wrote in this PR is 100% covered by test cases.

By that as well I meant the coverage report itself. you can see it shows the uncovered lines in the table that you attached.

I would really appreciate it if we have a consensus on what is expected to attach in the PR 🤝. Though I am adding what I get after running npm test.

we already have this, but some people tend to not understand the exact thing expected from that.

Add test coverage report only those files in which you have made some changes or added, please.

I see in test coverage for your 2 test files lines are skipped, please make sure your tests cover every line at least

Hey @Pratiyushkumar, What 2 test files are you talking about? Whatever code I have added is 100% covered. Please tag the line which you think is not covered.

I am talking about the coverage that you put in the description of the PR it doesn't give me any idea that your test cases are 100% covered.

Thank you for clearing my doubt, everything looks good to me
