fix(pdf): fix storage volume permissions blocking PDF generation

Named volume mounted root-owned over the app user's chown, so every
PDF (orçamento, fatura, download) failed with 500. Entrypoint now
fixes ownership on container start and drops to the app user.

feat(dashboard): decouple pipeline state from period filter

Status counts and recent OTs no longer disappear when an open order
was created before the selected period window.

feat(workorders): add vehicle/total columns, deadline urgency colors,
on-time delivery saldo and efficiency metric, plate search

Expose completed_at from wo_status_log so the frontend can compare
actual completion date against the deadline. Add "Eficiência de
Entrega" metric to Dashboard and Reports.

feat(reports): add dedicated vehicle service history report

New page with per-vehicle summary (OT count, total spent, last visit)
and full itemized service history with print output.

chore: relabel OT status "Concluir OT" -> "Concluída" and
"Iniciar Trabalho" -> "Em Progresso" (action buttons unchanged)
