Bug bash 2026-09-19: 17 bugs fixed and verified (BUGS.md)

Widgets: a bad pattern no longer silences every widget; malformed layouts load.
Shell: lost session returns to login at once; tab titles; Escape closes menus and dialogs.
Files: names are one path segment; unsaved edits ask before page/machine/tab changes;
only folders that opened are remembered. Terminals: unique default names; 64-char names.
API: queries capped at 10 000 values; 32 streams per client, 512 in all; only
/embed/widget is frameable. ZFS sensors: one unprivileged zpool list, no sudo journal spam.
Phone: 36 px inputs; dataset rows as wide as their cells. Machines: valid name pattern.
