I18n: extract and disambiguate a few messages

Extract:
- EEVEE: Compiling Shaders (the same message exists in EEVEE Next, but
  it uses string concatenation and I don't know yet how to deal with
  those--see T92758)

Disambiguate:
- Pan (audio, camera)
- Box (TextSequence)
- Mix (noun in constraints, GP materials)
- Volume (object type, file system)
- Floor (math integer part, 3D viewport horizontal plane)
  - Impossible to disambiguate the constraint name because
    bConstraintTypeInfo doesn't have a context field.
- Show Overlay (in the sequence editor, use the same message as other
  editors to avoid a confusion with the Frame Overlay feature, also
  called "Show Overlay")

Additionally, fix a few issues reported by Joan Pujolar (@jpujolar)
in T101830.
