Matches upstream owpengram/owpengram-server's version. v1.3.2 collapses the
old per-kind KeyboardButtonClass sum type (KeyboardButton, KeyboardButtonURL,
KeyboardButtonCallback, KeyboardButtonRequestPeer, ...) into two unified
structs mirroring Telegram's actual current MTProto layer: KeyboardButton
(reply keyboards) and KeyboardInlineButton (inline keyboards), each carrying
a Text/Style pair plus a Type field (ButtonTypeClass / InlineButtonTypeClass)
that now holds what used to be the concrete Go type.
Migrated the two call sites (internal/rpc/convert_markup.go,
internal/rpc/bots_longtail.go) and their tests to the new shape. Behavior is
unchanged -- every button kind (callback, url, url_auth, web_view,
switch_inline, copy, request_phone, request_geo_location, request_poll,
request_peer, simple_web_view) still round-trips the same domain fields,
just read from/written to Type instead of the button's own concrete type.
