infra/redroid: clean bad droplet name from 'lilith-store-redroid' to 'redroid' (and volume/firewall/container for consistency)

- Droplet: 'redroid'
- Firewall: 'redroid-fw'
- Volume: 'redroid-data'
- Container inside: 'redroid'
- Updated top comments, usage, volume mount refs.
- Note in IaC about previous bad name during store-vpc addition.
- This redroid is the shared execution backend for screening tools (mrnumber primarily); will be orchestrated by CT app post-subsumption of LP mrnumbers.
