Peter Woolery 56fc58b843 fix(tools): reject CSV metacharacters in flash_device.py inputs
device-id, location-id, wifi-ssid, and wifi-password were interpolated
directly into the NVS partition CSV. A value containing comma, double
quote, CR, or LF would split the field/row and silently provision the
wrong NVS keys — easiest concrete failure: a Wi-Fi password containing
a comma. Validate operator-supplied strings before generating the CSV.

Add an empty tools/__init__.py so the regression tests can import the
helper as 'tools.flash_device' (matches the existing 'server.*' test
pattern).
