Teaching four sections while finishing is not neutral, it is actively negative. I taught three in my last year and lost every morning to grading guilt. If you stay, negotiate down to two sections and see whether the department blinks.

Teaches four courses across two colleges and tracks every hour of it in a spreadsheet.
The "unless I hear otherwise by the 30th" line feels aggressive to me. Does it not read as an ultimatum from a student?
Completely normal and the comparison is unfair to you. Coursework writing is summarising things other people already established, which is fast. Dissertation writing is making a claim nobody has made and checking it holds, which is slow by nature. My final chapter averaged about 180 usable words a day over four months and it is the best thing I have written.
The appendix is your friend. Do the cheapest defensible version of the request, put it in appendix C with two paragraphs on what it does and does not show, and cite it in one line in the main text. A referee-style request is satisfied by evidence you engaged with it, not by six weeks of new pipeline. The second dataset one I would push back on directly: that is a second paper, not a robustness check.
Also worth checking whether your union or grad student association has a payroll contact. Ours had one person who could look up the actual transaction log and tell you which step stalled.
