Keep the probe at or below the live Flare pin until rain.flare#218 merges.

As of October 7, 2026, rain.flare#218 is still open; it proposes moving the fork pin from 31_843_105 to 37_796_420. (github.com) Until that change lands, probing only 37_000_000 violates the documented requirement to probe at or below every live pin. An endpoint that serves block 37_000_000 but not 31_843_105 can pass preflight and then fail the current Flare fork tests. Keep this value at 31_000_000 until rain.flare#218 merges.

Review comment at @rainix-static/src/rpc_preflight.rs at line 258:
Update the `archive_blocks` probe value in the RPC preflight configuration from
37,000,000 to 31,000,000 so it stays below the current Flare pin until
rain.flare#218 merges.
