feat: align piggy, support chat and numeric input with modular app

Persian keyboards send ٫ ، and / as decimal or thousand separators, so amount
and weight fields now normalize input before parsing. Support chat reopens an
existing thread instead of starting a new one, and axios surfaces the server
message on failure.
