feat: add cmd/form2mail using formmailer/ipcohort/geoip/gitshallow
Drop-in replacement for the legacy standalone form2mail binary.
Preserves CLI flags, env vars, .env loading, password prompt, response
file hot-reload, field mapping (input_1/3/4/5/7), rate limit (5/min,
burst 3), North-America country gate, .ru silent-drop, routes, startup
banner, and [REDACTED] placeholder for bot rejections.

Changes vs. legacy:
- Replaces embedded iploc with net/geoip (requires GeoIP.conf)
- Reads bitwire-it repo's native layout (tables/inbound/*) instead of
  a hand-managed flat inbound.txt
- gitshallow.Repo with GCInterval=24 keeps .git from accumulating
  orphaned blobs after hourly upstream updates

formmailer additions to support form2mail's legacy behavior:
- SuccessBodyFunc / ErrorBodyFunc — per-request body providers for
  hot-reloadable templates
- HiddenSupportValue — string to render in place of {.SupportEmail}
  for blacklist/bot rejections (form2mail uses "[REDACTED]")
