 34c9457c69 Remove TMM relayed-position precision clamp (#12039) 
The clamp rewrote the payload of relayed position broadcasts. The XEdDSA
signature covers Data.payload, so receivers that know the sender's key
dropped the rewritten packet. Relays now forward position payloads
unmodified.

Removes USERPREFS_TMM_APPLY_TO_PRIVATE_CHANNELS, which only gated the clamp.
