Subject: [PATCH] fix: increase max_request_body_size to 15 MiB

Solana accounts can be up to 10 MB. With base64/hex encoding overhead,
the JSON-RPC payload for a max-size account reaches ~13.5 MB, exceeding
the default 5 MiB limit and causing HTTP 413 during surfnet_setAccount
runbook execution. 15 MiB accommodates the largest possible account
with headroom.
