[AMORO-4368][Dashboard] Fix Tables menu navigation after viewing Hive tables

[csurong]

Why are the changes needed?

Clicking Tables after viewing a plain Hive table restores its cached identifier under /tables. This calls the generic details endpoint and reports that the table does not exist, although /hive/details loads it successfully.

Closes #4368.

Brief change log

Make the Tables sidebar entry return to /tables without table query parameters. Selecting a table still opens the appropriate details page, and the table tree continues to restore its expanded nodes from session storage.

How was this patch tested?

• Manually opened a Hive table, returned through Tables, and selected the table again. Its schema loaded successfully.
• Verified that the catalog and database nodes expand again after returning to the table browser.
• pnpm exec eslint src/components/Sidebar.vue
• pnpm build
• git diff --check
