fix tables route fallback when query table is missing

[Esubaalew]

invalid table query param can blank out the Tables page.

The code i am refering is this

const tab = table
  ? data.tables.findIndex(({ name }) => name === table).toString()
  : "0";

If the table name is not found maybe dropped, returns -1, so defaultValue becomes "-1". No tab/content has that value, so the tab content area renders empty.

How to reproduce this

create db and add some table and value: bash sqlite3 /tmp/sqlstudio_bug.db "CREATE TABLE users(id INTEGER PRIMARY KEY, name TEXT); INSERT INTO users(name) VALUES ('esube');"

Then open that table Open /tables?table=users

then manually change the url to somethung else /tables?table=does_not_exist
Page shows tab list, but no table content.

This change makes the non existing query as follows instead

Pull request overview

Fixes an issue in the Tables route where an invalid ?table= query param could select a non-existent tab (-1) and render an empty content area.

Changes:

• Adds logic to detect when the requested table name isn’t present in data.tables.
• Falls back to the first tab ("0") when the requested table is missing.
• Displays a “Table not found” message card when the query param doesn’t match any table.
