* ISSUE-22596: Fix search alias resolution with clusterAlias configuration
**Problem:**
MCP SearchMetadataTool was failing with "Failed to find index table" error
in production environments when clusterAlias is configured, while working
correctly in development environments without clusterAlias.
**Root Cause:**
- SearchMetadataTool was directly using entity alias names (e.g., "table")
without applying the clusterAlias transformation
- When clusterAlias is configured, both search indices and their aliases
are created with the cluster prefix
- Without this transformation:
- Development: "table" alias exists ✅
- Production: only "openmetadata_table" alias exists, "table" doesn't ❌
**Solution:**
- Apply SearchRepository.getIndexOrAliasName() transformation to respect clusterAlias
- This ensures the correct alias name is used ("table" → "openmetadata_table" in production)
- Add enhanced logging to track alias name resolution
**Testing:**
- Added unit tests covering scenarios with and without clusterAlias
- Verified fix resolves production issue with clusterAlias="openmetadata"
**Impact:**
- Fixes MCP search functionality in production environments using clusterAlias
- No breaking changes to existing functionality
- Maintains backward compatibility with environments without clusterAlias
