fix(ssr): stop content-card forcing always-on scrollbars; add tmp/ scratch dir

content-card used `overflow-scroll`, which renders scrollbar tracks even
when the content fits — visible as superfluous bars around the admin chart
cards. Switch to `overflow-auto` so scrollbars only appear when content
genuinely overflows (e.g. wide data tables still scroll).

Also add a gitignored ./tmp/ scratch directory (tracked via .gitkeep) and
document in AGENTS.md that temp files belong there.

+## Temporary Files
+
+Write any temporary files (screenshots, scratch logs, generated artifacts, etc.) to the `./tmp/` directory at the repo root. Its contents are gitignored (only `.gitkeep` is tracked), so nothing there will be accidentally committed. Do not scatter temp files elsewhere in the repo or in the system `/tmp`.
