Replace the `realpath -m` confinement check with a POSIX sh script that
uses `readlink -f`, which BusyBox (Alpine) also provides. The script
walks up to the deepest existing path, resolves it, and appends the
missing rest. It fails closed on dangling symlinks and on `.`/`..` in
the missing part.
Send the script as a single `sh -c '<script>' sh <base> <path>` line so
the non-root sudo parser only adds sudo in front of it and does not
rewrite `$(...)`, `&&` or case statements.
Add unit tests that run the command with GNU and BusyBox tools, as root
and through the sudo parser, against a real symlink tree. Update the
feature test fakes to match the new command.
Eager-load S3 on volume backup lists and add an S3 status column with
Configured/Unavailable/Not set badges. Surface Local vs S3 on the
persistent storages backup column. Move service resource domain links
to a globe action in the card footer, and update related tests and grid CSS.
Move profile email change into a modal with Alpine focus/close handling,
show a loading overlay during command-palette navigation, and adjust
volumes/config-diff grids plus related service/storage UI. Cover with
feature tests for search, profile, storage, and domains.
Improve project resource UIs: sort domains by DNS failure, stop re-adding www pairs on refresh, lazy-load storage tabs with counts, tighten env-var tables, keep application tabs active across Livewire polls, unify database type labels, and update related CSS/JS and tests.
