Improve tab behavior for database tables

[robinmiau]

When opening a database table in DBCode, each table opens in a new tab that remains open permanently. This differs from VS Code’s default behavior, where tabs only stay open if pinned, double-clicked, or interacted with.

As a result, opening multiple tables quickly leads to tab clutter that must be manually cleaned up.

Suggestion: Align DBCode’s tab behavior with VS Code’s preview tab system, where tabs are temporary unless explicitly pinned, double-clicked, or interacted with.

It would also be useful to have an option to reuse a single tab for DBCode views. Setting a fixed tab title does not currently prevent new tabs from being opened for each table.

I have released 1.29.4 which has better logic around this. Webviews don't have the same preview concept as files do in VSCode so they wont show italic text, but I track it by if you open with a single or double click and if you interact with the content, that will trigger it to be kept rather than recycled on next open.
