[feat]: Enhanced Search - Right Click Find entities named [column name|table name|index name|view name|udt name|udt field name|keyspace name etc..]

[millerjp]

Enable users to discover any schema entity containing a specific name across the Cassandra database.

This is the first path on an enhanced search feature in the UX - eventually supporting regex type searches, different cases etc.. in a traditinal find type of feature you see often in dev desktop apps.

Feature Description
Right-clicking a column, table etc.. will present a "Find entities named [column name, table name etc..]" option that performs a case-insensitive search across the entire schema. The search will locate the name in:

• Column names
• Table names
• Materialized View names
• Secondary Index names
• Secondary indexes on columns with the same name
• User-Defined Type names and fields
• Any other schema entities

Business Value
This feature facilitates:

• Quick discovery of related data structures through naming patterns
• Name uniqueness validation before implementing new entities
• Comprehensive schema exploration and documentation

Implementation Details
The search functionality will:

• Execute a case-insensitive match for the selected name in the cluster schema
• Display consolidated results showing all matching schema entities
• Group results by entity type for improved readability
