FIX-48: Dedicated ه→ة pass for IV words (الحكومه→الحكومة)

OOV cleanup can't fix words like الحكومه and الشركه because they're IV
in the BERT vocabulary. This dedicated pass runs on ALL words (not just
OOV) and converts ه→ة when:
1. Word ends in ه preceded by a consonant
2. The ة form is also IV
3. Word is not in protected list (فيه, عليه, له, etc.)

Targets PC034 (الحكومه) and PC035 (الشركه).
Tests: 39 passing.
