cjkas c1b47f898c fix: give every NVS user its own Preferences handle
loop() and the async web server task shared one global Preferences.  A
begin() from one task failed while the other had a namespace open, and the
clear() or remove() after it then hit the other task's namespace: saving the
radio settings while a command committed its rolling code could erase every
rolling code.

Each function now opens NVS with a local Preferences.  NVS serializes access
internally and the destructor closes the handle, so no lock is added (see
docs/adr/0001).  No new tests: nothing here builds natively, and deleting the
global makes any missed use a compile error.

The read-then-commit races on rolling codes across tasks remain and are
tracked in docs/KNOWN_ISSUES.md.
