README should not overstate list-and-create APIs as CRUD routes

[TheGreatAion]

Parent bounty: #743

Documentation bug

The README backend overview says the API includes:

- CRUD routes for users, jobs, and proposals

However, the current routers only expose list and create handlers for those resources:

userRoutes.get(/, getUsers);
userRoutes.post(/, postUser);
jobRoutes.get(/, getJobs);
jobRoutes.post(/, postJob);
proposalRoutes.get(/, getProposals);
proposalRoutes.post(/, postProposal);

There are no update or delete handlers in those routers. Calling the surface CRUD overstates the implemented API and can mislead contributors who use the README as their orientation guide.

Expected behavior

The README should describe these resources as list and create routes until the remaining CRUD operations exist.

Scope

• Replace the inaccurate CRUD wording with an accurate list-and-create description.
• Keep the patch limited to this README correction.
• Do not add API routes, change controller behavior, or modify unrelated documentation.
