feat: add client-side text search to KIP and FLIP tables

[akpmohan07]

What

Adds a real-time text search input to the KIP and FLIP table filter controls.

Supported Columns:

• Descriptions
• IDs (KIP and FLIP)

How

• Added search input to buildFilterUI() in table-filter.js
• Search filters rows by matching against KIP/FLIP ID and description columns
• Search and dropdown filters are combined with AND logic
• Clear Filters button resets search input alongside dropdowns
• Case-insensitive matching using toLowerCase() + includes()

Testing

• Partial word search works (e.g. "replicat" matches "replication")
• Case insensitive (e.g. "CONSUMER" matches "consumer")
• Combined filter + search narrows results correctly
• Clear button resets everything

Search By Name

Search By ID
