Fix: Back navigation freezing on /editor after adding tables (#687)

[krishx06]

Fixes #687

Summary:
Fixes the issue where the browser’s Back button freezes or skips pages after adding a table in the /editor view.

Problem:

• Each autosave triggers save() in Workspace.jsx, which always calls setSearchParams(searchParams); even when no URL changes are needed.
• This pushes a new /editor entry to browser history on every save, causing the Back button to become unresponsive or require multiple presses.

Solution:

• Only call setSearchParams() when shareId exists in the URL.
• Use { replace: true } to replace the current history entry instead of pushing new ones.

if (saveAsDiagram) {
  if (searchParams.has("shareId")) {
    searchParams.delete("shareId");
    setSearchParams(searchParams, { replace: true });
  }
}

Result:

• No duplicate /editor entries in browser history.
• Back navigation now works smoothly after adding tables.
• Autosave and URL updates remain fully functional.

Verification:

1. Navigate from / → /editor.
2. Add a new table (triggers autosave).
3. Press Back → returns immediately to /.
4. Repeat to confirm consistent behavior.
