feat: Regular Time entry support with name resolution

[shaank0]

Summary

• Regular Time entries — autotask_create_time_entry can now create time entries not tied to a ticket, task, or project (for meetings, admin work, training, etc.)
• Name-based resolution — accepts resourceName (e.g., "Will Spence") instead of requiring numeric resourceID
• Category selection — accepts category (e.g., "Internal Meeting") instead of requiring numeric internalBillingCodeID
• Smart prompting — when resource or category is missing, returns available options instead of failing
• Billing code stubs implemented — searchBillingCodes() and getBillingCode() now work instead of throwing "not available" errors

Example usage in Claude Desktop:

"Log 1 hour of regular time for Will Spence, internal meeting, summary: B and I meeting"

Depends on

• feat: Regular Time entry support with name resolution helpers autotask-node#153 (SDK helpers for name resolution and Regular Time)

Test plan

• Create Regular Time entry with resourceName + category (both resolved automatically)
• Verify prompting when no resource specified → lists prompt for name
• Verify prompting when no category specified → lists available categories (Internal Meeting, Training, PTO, etc.)
• Verify ticket-scoped time entries still work unchanged
• Verify task/project-scoped time entries still work unchanged
• Verify invalid resource name returns helpful error
• Verify invalid category name returns list of valid options

Thanks for the contribution @shaank0! The Regular Time entry feature is a great addition. However, there are some blockers before this can be merged:

Blockers

1. Dependent SDK PR is closed. This PR depends on wyre-technology/autotask-node#153, which is closed (not merged). The SDK methods this relies on (createRegularTimeEntry(), resolveResourceByName(), getInternalBillingCodes(), etc.) don't exist, so all new code paths will throw at runtime.

2. CI is failing. The existing test should handle unsupported entity methods with proper error messages expects getBillingCode() to throw "Billing codes API not directly available", but the PR changes that method to call the (non-existent) SDK. The test needs updating.

3. No new tests. The PR adds substantial new logic (name resolution, category resolution, prompting flow, three distinct createTimeEntry paths) but includes zero new tests.

Other Notes

• Heavy use of (client as any) casts — understandable if the SDK types aren't updated, but means zero compile-time safety
• searchBillingCodes ignores its _options parameter entirely
• Handler mutates the a (arguments) object directly with delete — fragile if the framework ever freezes or logs args after the handler

Next steps: Please get the SDK PR (autotask-node#153) reopened and merged first, then update tests and we can move forward. The architecture and approach look solid otherwise.
