fix: falsy details/actor render + critical() delegates to _send (dpylogger-2/3)

- dpylogger-2: build_embed/_emit_stdlib test 'is not None' so falsy-but-valid values (0,
  False) render; only None or '' is dropped/substituted.
- dpylogger-3: critical() delegates to _send (via a new content= param) instead of
  hand-mirroring the send/error scaffolding — single source of truth.
