[ISSUE #2453] fix(consumers): canonicalize delivery order type

[yuluo-yx]

Summary

• submit MESSAGES_ORDER from the consumer creation form
• accept the documented CSV value
• canonicalize the legacy spaced CSV value before import

Verification

• ConsumerPage and resourceCsvImport: 27 tests passed
• targeted ESLint and Prettier checks passed
• scope check: 80 changed lines

Fixes #2453

Summary

Good catch on the space-vs-underscore inconsistency in MESSAGES_ORDER. The backward-compatible normalizeDeliveryOrderType in CSV import ensures existing imports with the old space-separated value still work. Test coverage for both forms is solid.

LGTM.
