Resolve bare Actor names in build-actor, call-actor, and the other Actor tools #1614

What happens

The versions tools (#1453, #1454) take a bare Actor name such as my-actor and resolve it to the Actor of that name in the caller's account. build-actor, call-actor, fetch-actor-details, get-actor-build-list, and get-actor-run-list take only an ID or username/name, so the same name fails there with "Actor 'my-actor' not found."

Local evals of the versions tools (create, fix, and change an Actor, then build and run it) on Haiku 5.5, Sonnet 5.5, and Opus 4.8 hit this in 7 of the 8 tool errors across 15 trials. The agents reused the bare name the versions tools had just accepted, and each recovered on the next call with username/name.

Fix

Resolve a bare name with the shared getResourceByIdOrName (src/utils/apify_resource_id.ts) in every tool that takes an Actor:

• build-actor, get-actor-build-list, and get-actor-run-list, in feat!: Add create-actor and update-actor-version tools #1453.
• call-actor and fetch-actor-details, in a separate PR, since they use the shared Actor definition cache and the payment checks, and call-actor can start a paid run. A bare name means the caller's own Actor, never a Store Actor.
• delete-actor, later.
