fix(oc-capability): uses correct room field types

[alperozturk96]

Fixes

forbiddenFileNameCharacters, forbiddenFileNames, forbiddenFileNameExtensions, forbiddenFilenameBaseNames

This PR fixes an inconsistency where several capabilities columns were defined as INTEGER in Room but actually stored JSON String values.

Why it previously worked

Data was read via cursor (getString), bypassing Room’s type mapping

Changes

Updated affected fields in CapabilityEntity from Int? to String?
Added a migration that drops the capabilities table to ensure a clean schema
Adds capability dao and mapping between entity and OCCapability
