fix(sports): per-type warning cooldowns and font-load logging

Follow-ups from the second review pass, both on already-fixed findings:

_should_log accepted a warning_type and ignored it, sharing one
timestamp across every kind of warning -- so an API-error warning
silenced an unrelated cache warning for the next minute, and whichever
fired first won. Cooldowns are now keyed by type. Nothing in core calls
this method, so no behavior regressed; _last_warning_time is kept in
step for subclasses that read it directly.

_load_fonts logged through the module-level logger, dropping the manager
context, and had no return type hint. It now uses self.logger (set well
before _load_fonts runs) and names the directory it searched -- the bare
"Fonts not found" sent people hunting for a font-format problem when the
actual cause is an install missing assets/fonts.

Gates: 717 core unit, 66 plugin safety.
