docs(asg,ecs): fix incorrect CLI examples and add missing Usage blocks

[amaechiabuah]

Describe Changes

Resource-specific docstring fixes for the asg and ecs resources. Scope deliberately excludes the shared template-mechanism issue (where inherited V2/V3 docstrings render the wrong CLI name for some resources) — that's a follow-up PR.

asg

• create docstring showed duploctl hosts create — corrected to duploctl asg create.
• scale docstring advertised a non-existent -n <name> flag (customer got unrecognized arguments: -n). Updated to positional usage.

ecs

Audited every @Command in ecs_service.py; 8 of 14 had no Usage: CLI Usage block. Added blocks for create_service, update_service, update_taskdef, delete_service, find_def, find_def_by_arn, find_service_family, and find_task_def_family.

Also caught a latent bug: list_task_def_family referenced a non-existent duploctl ecs list_definitions command in its example. Fixed to use the actual method name.

Docs-only change — no code behavior changed, so no new tests. Verified mkdocs build emits no new griffe warnings for the touched files, and the existing unit tests for asg/ecs still pass.
