- relay: key uploadables map by actual variable name instead of iteration
index so order-mismatch between Object.keys passes can't desync the
multipart map from form field names
- mcp/v1: drop dead commented middleware line
- DurationPicker: tighten parse regex to require PT prefix for M/H and P
for D/W, and reject NaN in stringify so cleared inputs don't produce
invalid duration strings
