FE: Column Filtering Support for Kafka connects table

[Vixtir]

• Breaking change? (if so, please describe the impact and migration path for existing application instances)

What changes did you make? (Give an overview)

What’s Added

• Extended column meta definition for TanStack Table with a new property:
  meta.filterVariant?: 'multi-select'

• Added support for column-level filtering based on filter variant.

How to Enable Filtering for a Column

A column that supports filtering must define:

• accessorKey
• meta.filterVariant e.g. 'multi-select'
• filterFn (e.g. 'arrIncludesSome')

Example

const kafkaConnectColumns: ColumnDef<FullConnectorInfo>[] = [
  {
    header: 'Connect',
    accessorKey: 'connect',
    cell: BreakableTextCell,
    meta: { filterVariant: 'multi-select' },
    filterFn: 'arrIncludesSome',
  }, ...
]

URL Filter Persistence

Introduced queryPersister to sync filters with the URL.
This avoids polluting the main Table component with filter state management logic.

Columns filtering Persistence logic is extracted intoFilter/lib/persistermodule.

All persisters implement the following interface:

export interface Persister {
  getPrevState: () => ColumnFiltersState;
  update: (nextState: ColumnFiltersState, resetPagination?: boolean) => void;
}

The approach is scalable — new filter variants or persisters (e.g., localStorage, session, or in-memory) can be added with minimal changes.

Pagination can optionally be reset on filter change via the resetPagination argument.

Is there anything you'd like reviewers to focus on?

need rename folder FIlter to Filter to (frontend/src/components/common/NewTable/Filter)

there’s a layout issue with the connector name column width.
if a connector has a long topic name, the connector name column becomes too narrow, while the topics column gets overly wide:
