Add share-log subcommand to upload install.log to paste.rs (#4511)

* Add --share-log flag to upload install.log to paste.rs

* Apply ruff-format to share_log.py

* Rework share-log per review: subcommand, TUI confirmation, truncate large logs

* Replace curl/SysCommand with urllib.request, remove defensive try/except

Per review: use stdlib urllib instead of shelling out to curl,
drop unnecessary try/except around TUI confirmation,
remove tempfile (content is passed directly as bytes).

* Fix TUI imports after ui module was pulled one level up (#4515)

* Decouple share_install_log from TUI module

* Add unit tests for share_install_log function

* Update docs to use share-log subcommand syntax

+   | An easy way to submit logs is ``archinstall share-log``, which uploads ``install.log`` to paste.rs and prints a shareable URL.
