[FEATURE]: Support Multi-Organization Contributor Filtering

[jikrana1]

Feature and its Use Cases

Allow users to select and filter contributors from multiple organizations at the same time.

Currently, the Contributors page allows selecting only one organization at a time. This feature would allow users to select 2 or more organizations and view their combined contributor data.

Example

For example, if a user selects:

• google
• apple

the Contributors page should display contributors belonging to either google or apple.

Similarly, if the user selects 3 organizations, contributors from all 3 selected organizations should be included in the results.

If only one organization is available, the multi-organization selection option should not be shown, since there is nothing to select multiple from.

Use Cases

• Compare contributors across multiple organizations.
• Find contributors from selected organizations.
• Combine multi-organization filtering with username search and sorting.
• Easily clear the selection and return to all organizations.

Additional Context

The feature should work with the existing contributor search, sorting, and analytics functionality.

The UI should clearly show which organizations are currently selected and should avoid unnecessary API requests by using the existing contributor data where possible.

Code of Conduct

• I have joined the Discord server and will post updates there
• I have searched existing issues to avoid duplicates
