server: fix mangled Stripe metadata string literal in checkout test
f82abccd (lint/fmt sweep) rewrote the storage_limit_bytes metadata value
"1073741824" as "1_073_741_824", applying numeric-literal underscores to
a string. parse::<u64>() rejects underscores, so from_metadata returned None
and synckit_app_sub_reads_interval_key failed. Stripe metadata never carries
underscores; revert the string to plain digits.
