db: migration session_default_notes_field + schema regenerado

Migration 20260511000001 adiciona campo 'notes' (Observacao, textarea,
sort_order=30) como campo extra default no commitment determinado 'Sessao'.
Antes Sessao era a unica excecao entre os nativos — Leitura/Supervisao/
Aula/Analise ja tinham. Padroniza pra que a Observacao da sessao siga o
mesmo mecanismo de extra_fields dos outros, e o frontend remova a textarea
hardcoded do AgendaEventDialog (proximo commit).

Backfill: insere 'notes' em TODOS os commitments Sessao ja existentes
(idempotente). Forward-fix: substitui a funcao seed_determined_commitments
incluindo o bloco de Sessao + 'notes' pra novos tenants.

Schema regenerado via db.cjs schema-export pra refletir o estado pos-
migration. agenciapsi-db-dashboard.html regenerado pelo
generate-dashboard.cjs.
