ux(sqlite): the table chips on the Overview page look clickable but do nothing #1816

Problem

The SQLite Overview page lists the tables as chips with a table icon (orders, products, users in the Demo Playground). They look like buttons, but they are plain text: no hover state, no click action, no semantics action (a semantics snapshot shows them as text, not tappable).

Proposal

Make a chip open the table in the table browser (the same as choosing it in the sidebar tree), with the kit's hover and focus states and a tooltip. A context menu with Open, Open in SQL (SELECT …) and Copy name would match the tree.

If they are meant to be a read-only list, render them without the chip look so they do not invite a click.

Where

lib/features/sqlite/sqlite_overview_tab.dart (the Tables card). Check the PostgreSQL / MySQL overviews for the same pattern.

Acceptance

• Clicking a table chip opens that table (or the chips no longer look clickable).
• Hover, keyboard focus and a semantics label with an action.
