Size the execution node for production: cx43

[anuveyatsu]

Promotion to production: the box will carry real client work (concurrent build-heavy agents plus the control plane), so cx33 to cx43 (4 cores/8 GB to 8 cores/16 GB, EUR 8.49 to 16 a month) for headroom rather than leaning on swap.

Applied targeted at the server (0 added, 1 changed, 0 destroyed). Verified after the reboot: 8 cores, 15.6 GB RAM, 4 GB swap, dispatcher active.

Update the execution server comment.

The comment still describes 2 vCPU / 4 GB at EUR 5.49/mo. The cx43 value provisions the 8 vCPU / 16 GB server described by this change at EUR 16/mo. Update the comment to match the committed capacity and cost.
