Fix #5870: stale skills panel data on tab reopen (#5876)

Remove early-return guard in loadSkills() that skipped both API re-fetch
and renderSkillsList() when the Skills tab was reopened after first load.
The cascade entrance animation is already handled inside renderSkillsList()
via _cascadeNext, so the guard was unnecessary and caused deleted/edited
skills to remain visible until a full page reload.
