fix(precedent-edit): translate appeal_subtype enum values to Hebrew

The metadata extractor occasionally stuffs the practice_area enum
(``betterment_levy``, ``rishuy_uvniya``, ``compensation_197``) into
the free-text ``appeal_subtype`` column. The edit sheet then showed the
raw English string in the "תת-סוג" input.

When initialising the form, run the value through ``appealSubtypeLabel``
which maps known practice-area enum values to their Hebrew label and
returns anything else unchanged. The user can then edit normally; on
save the Hebrew sticks, so the next view is also clean.
