fix(plugin-clipboard, preset-gfm): fix pasting multiple tables from Google Docs

[Saul-Mirone]

Closes #2259

The previous fix (#2283) resolved Case A (pasting a single table) but Case B (pasting a full document with multiple tables and text) was still broken — only the first table was parsed correctly, and remaining tables became plain text.

Root cause:

1. Google Docs wraps all pasted content in <b style="font-weight:normal;" id="docs-internal-guid-..."> with <div> wrappers around each table. ProseMirror's parseSlice fails to parse the second table inside these wrappers, breaking it into orphaned table_row nodes and empty paragraphs.

2. The clipboard plugin was re-parsing the HTML independently (ignoring ProseMirror's pre-processed Slice), which bypassed both transformPastedHTML and the paste rules (transformPasted).

Fix:

• Add transformPastedHTML in the clipboard plugin to strip Google Docs <b> and <div> wrappers before ProseMirror parses the HTML.
• Use ProseMirror's pre-processed Slice (3rd arg to handlePaste) when HTML is present, instead of re-parsing.
• In the table paste rule, detect orphaned table_row nodes at the top level of a fragment and re-wrap them into proper tables.
