Gateway config now warns admins when a pricing multiplier above 1 is set as a markup
What
When a gateway's pricing.multiplier setting is greater than 1, config validation now emits an admin-facing warning. It notes that the value acts as a markup, that spend limits are counted at the marked-up rate, and that clients running a version before v2.1.270 ignore a multiplier above 1.
Why
This helps admins understand that setting a multiplier above 1 changes how spend limits are calculated, and flags a compatibility gap for older clients that won't respect the markup.
