RollyPay (and 5 others) showed buttons but triggered "payment methods
unavailable" because get_available_payment_methods() was missing them.
The keyboard builder (inline.py) had all providers, but the text
generator (payment_utils.py) did not — divergent hand-maintained lists.
Added to all 4 functions: get_available_payment_methods,
is_payment_method_available, get_payment_method_status,
get_enabled_payment_methods_count:
- SeverPay, PayPear, RollyPay, Overpay, AuraPay (new)
- RioPay (was in methods list but missing from status/count)
