fix: read signature dimensions from capabilities without fallback

Remove invented numeric fallbacks (175/100/350) and double-sanitization
from all five components that read signature dimensions from the
sign-elements capability block.

The dimensions are always populated by the server (required fields in
the OpenAPI schema). A zero or absent value should surface as a real
error rather than be silently replaced with a made-up constant that
only matches one render mode.
