Add all DAO proposal filter

[dnlbui]

What Changed

This PR adds an All option to the DAO proposal filters so users can view every proposal in the selected Active or Archived group.

• Adds All as the last option in the expandable second filter row, with a count for the selected group.
• Makes All bypass lifecycle-status filtering while preserving the existing newest-first ordering.
• Keeps the second row expanded while All is selected so the active filter remains visible.

Fixed Flow

1. The user expands the second proposal-filter row.
2. The user selects All.
3. The list includes proposals across every lifecycle status in the selected Active or Archived group.
4. The All count and selected state remain visible in the expanded row.

Why

Previously, every available option restricted the list to one lifecycle status or the special Claimable view. Users had no way to see all proposals in the selected group without switching between filters.

Validation

• node --check app.js
