feat: multi-calendar CalDAV sync + macOS install script

org-caldav:
- Sync personal calendar (twoway) + family calendar (fromcal/read-only)
- Clean helper fns: my/caldav-get-password, my/caldav-register-digest
- authinfo: add 'family' entry for family calendar password
- ~/.authinfo: machine cal.apps.sukany.cz login family password PASS

macos-install.sh:
- Bootstrap script for fresh macOS: brew, Emacs prereqs, search tools
- Perl (cpanm + LSP/Tidy/Critic), Python (ruff/pyright), Go (gopls)
- Ansible, Terraform, Podman, Kubernetes, email (mu/isync)
- Doom Emacs setup guidance
