Problem
Currently, in Assets, when configuring an Asset custom field from the field context, Jira automatically sets the first/top value as the default.

Suggested Solution
Provide an option in the Asset field configuration to manually choose one or more default values.

• Admins should be able to select a default value from the available asset objects (just like we can in single-choice or dropdown fields).

• If multiple field contexts exist, each context should allow a separate default to be defined.

• Ideally, this should also support conditional defaults (e.g., per project, per request type).
