v0.52.3

Fixed — 0.52.2's Solana image fix cut the paid submit off at 30s

0.52.2 moved blockrun_image on the Solana wallet rail onto the async helper
so a long render is polled instead of lost. It kept the helper's 30s submit
timeout, which is sized for video's 3-20s enqueue. The image route holds the
paid POST for up to ~30s and only then answers 202 { id, poll_url } — so the
client aborted at the moment the job id was due, after the transfer had
settled. The fix did not reach the case it was written for, and a render that
finished inline just past 30s (which 0.52.1 delivered) was now lost as well.
The image submit now waits 95s, the account rail's timeout for the same 30s
window.

Fixed — an edge 5xx on a Solana video submit no longer books a phantom charge

0.52.2 kept the payment tracker armed on any 502/503/504 at a Solana async
submit, because on image and music the submit settles the transfer. Video
settles on the poll that observes completed, so its submit cannot have moved
money — yet the full estimate was booked against the budget and the tool said
the charge might stand. Each caller now declares whether its submit can settle
(submitMaySettle, default true); video declares false.
