ui: make search placeholder in service main tabs dynamic

[harsh-vador]

Describe your changes:

Fixes #26510

Issue

The search bar placeholder in service details pages (such as Database Service, API Service) was using the service type name template (e.g., "Search for Database Service"). This was slightly confusing since users are searching for the assets listed in the table (like Databases, Topics, or Collections), rather than searching for the service itself.

Solution

Updated the search placeholder to be dynamic based on the asset type and tab label. It now correctly populates with corresponding labels, such as:
"Search for Databases" (for Database Service)
"Search for Topics" (for Messaging Service)
"Search for Collections" (for API Service)
This matches the active tab name exactly, making the search bar fully intuitive for users.
