fix(send): run post_send_actions after retried sends

A task only reaches the queue after a failed send, so the fresh attempt
never ran post_send_actions (edit-before-forward prompt / channel
forward) — it failed before that point. The old guard skipped
post_send_actions for resumed tasks (batch_index > 0 or sent ids
present), which meant any send that needed a retry after partial
progress silently lost its forward and edit prompt.

post_send_actions is now run unconditionally on a successful queue send;
it executes exactly once, after the whole sequence completed.
