fix(owlry-core): make ProviderFilter dynamically accept all plugin types

Replace hardcoded list of 13 plugin IDs in ProviderFilter::all() with
an accept_all flag. When set, is_active()/is_enabled() return true for
any ProviderType, so dynamically loaded plugins are accepted without
maintaining a static list. Prefix-based filtering still narrows scope
as before, and from_mode_strings() still filters to explicit modes only.
