Issue Title: Implement Job Filtering and Search Functionality

Issue Description:

As a freelancer, I want to filter and search for job postings based on specific criteria so that I can quickly find relevant opportunities that match my skills and preferences. This functionality should allow users to filter jobs by various parameters and perform keyword searches.

Tasks:

1. Implement Job Search Endpoint:

   • Create an endpoint to allow freelancers to search for jobs using keywords.
   • Support searching by job title, description, and other relevant fields.

2. Implement Job Filtering:

   • Create filters for the following criteria:
     • Job type (Hourly, Fixed)
     • Budget range
     • Job status (Open, In Progress, Completed, Cancelled)
     • Creation date range

3. Combine Search and Filter:

   • Create a single endpoint that supports both search and filter criteria, allowing freelancers to retrieve a filtered list of jobs based on their input.

Acceptance Criteria:

• Job Search:

  • Freelancers should be able to make a GET request to /jobs/search with query parameters for keywords.
  • Return 200 OK with a list of matching jobs or 204 No Content if no jobs are found.

• Job Filtering:

  • Freelancers should be able to make a GET request to /jobs/filter with query parameters for different filtering options.
  • Return 200 OK with a list of filtered jobs or 204 No Content if no jobs match the criteria.

• Combined Search and Filter:

  • Freelancers should be able to make a GET request to /jobs with both search and filter parameters.
  • Return 200 OK with a list of jobs that match the search and filter criteria.
