style: Integrate search form and table into single card container

- Consolidate filter/search form with data table in one card
- Separate with <hr class='my-0'> for visual hierarchy
- Remove redundant card-mb spacing and gaps
- Unified layout for Blog, Clients, Inquiries pages
- Cleaner, more cohesive data display

Applied to:
- Blog/Index.cshtml
- Clients/Index.cshtml
- Inquiries/Index.cshtml

Announcements and Faqs already have integrated structure (no search form)
