Thanks for submitting this PR! When we review PRs, we follow the Pipedream component guidelines. If you're not familiar, here's a quick checklist:

• Create components to address specific use cases whenever possible
• Component keys should follow the format app_name_slug-slugified-component-name
• Components should follow the standard directory structure
• Prefer Node.js client libraries to REST APIs
• When making API requests, handle pagination to ensure all data / events are processed
• Use secret props to capture sensitive data
• Props and methods should be defined in app files whenever possible
• Document methods with JS Docs
• Use optional props whenever possible, and set a default value where you can
• Use async options to accept user input wherever possible

Warning

Review ran into problems

🔥 Problems

Stopped waiting for pipeline failures after 30000ms. One of your pipelines takes longer than our 30000ms fetch window to run, so review may not consider pipeline-failure results for inline comments if any failures occurred after the fetch window. Increase the timeout if you want to wait longer or run a @coderabbit review after the pipeline has finished.

- Line 6: Update the action description in get-ebitda-estimate.mjs to follow the
agent-friendly structure: start with a one-line purpose (what the action does),
add a brief "When to use" sentence describing the use case, include a
"Parameters" note listing expected inputs/format (e.g., symbol, fiscalPeriod,
etc.) and any gotchas (rate limits, missing data), then finish with the existing
"[See the documentation](https://finnhub.io/docs/api/company-ebitda-estimates)"
link; modify the description field in the action metadata so it contains these
sections in plain text prior to the docs link to improve agent guidance.

In `@components/finnhub/finnhub.app.mjs`:
- Around line 49-56: Update the freq prop description to explicitly enumerate
allowed values and show an inline example so agents format input correctly:
change the description for freq (the property defined as freq with options:
constants.FREQUENCIES) to list the concrete allowed values (e.g., "allowed:
annual, quarterly, monthly") and include a short example like "e.g., 'annual'".
Ensure the text remains a single sentence describing allowed values and the
example.

Hi @Aldebaran638, thank you for your contribution! Looks good to me. Waiting on further steps before I approve and move this to QA, since this requires Finnhub premium.
