Search jobs by company without date filters - new `company_domain_or` and `company_linkedin_url_or` options

Previously, when using the Jobs Search endpoint, you needed to include at least one of these required filters:

• posted_at_max_age_days
• posted_at_gte
• posted_at_lte
• company_name_or

We've expanded the list of required filters to include two new options:

• company_domain_or
• company_linkedin_url_or

Now you can search for jobs from specific companies using their domain or LinkedIn URL, without needing to specify dates or company names. This gives you more flexibility when targeting jobs from particular organizations.
