Exclude locked elements from meditation eligibility.

If a circle offers only a locked element, canGainResonance can return true, but AttunementCaptureService.credit rejects every hit. The sit starts and can consume focus without raising resonance. Pass the player into this eligibility check and apply the same unlock rule before accepting the sit. The command change that lets staff set locked elements does not change the meditation credit rule. citeturn0search0

@src/main/java/net/tfminecraft/magic/meditation/MeditationCircle.java at line
182:
Update the meditation eligibility check around ElementRegistry.getById so it
receives the player and excludes elements they have not unlocked, using the same
unlock rule as AttunementCaptureService.credit. Ensure a circle offering only
locked elements cannot pass canGainResonance or start a sit that consumes focus.
