Refine email-proposal review UX (v0.1.0:91)

Three post-smoke refinements to the Matrix email-proposal review:

1. Dash separators (bot): every card/reply is framed with a dash rule top and
   bottom so threads stop bleeding together vertically on mobile.

2. Remove decided threads (bot): on a conclusive approve/dismiss from either
   surface, the bot redacts the card (client.room_redact) so the room clears
   down to only undecided items. Redacting the bot's own card needs no power;
   the web->Matrix path now redacts instead of posting a closure note.

3. Clearer note wording (server v91 + bot): the proposed grid note now names who
   emailed whom -- "{teammate} emailed {investor}" (outbound) / "{sender} emailed
   the team" (inbound) -- instead of an ambiguous "Sent"/"Received". Outbound
   detection also matches our corporate domain (public providers excluded), so a
   teammate's mail from a non-enrolled @ten31.xyz address no longer reads as
   "Received". Going-forward only; no schema change. The card drops its bare
   direction label since the note now carries the relationship.

Tests updated; 30/30 green, render-smoke green.
