Add ROR Support for Institutions

[whomingbird]

ROR (Research Organization Registry) is an open, community-driven registry of research organizations worldwide. It provides a unique, persistent identifier (ROR ID) for institutions, making it easier to disambiguate organizations in research data. ROR IDs are openly available, interoperable with other identifier systems (like ORCID and CrossRef), and designed for integration into research workflows.

This PR introduces ROR support in the institutions module. Users can enter institution data in three ways:

• Search by Institution Name – Type the institution's title and select it from the suggested list.
• Enter a ROR ID – Retrieve institution data by entering its ROR ID.
• Manual Entry – If the institution does not have a ROR ID, manually fill in the required fields.

The metadata for options 1 and 2 is fetched directly from ROR's API.

Additionally, ROR integration has been extended to project creation, enabling users to associate projects with institutions—either from locally stored data or dynamically fetched from ROR.

Improvements in Details

• Database
  Added a new column ror_id to the institutions table.
  Ensured ror_id is unique for institutions.

• UI
  Added the new input field of ROR ID
  The ROR ID is displayed as a clickable link in the institution details.
  Added a "clear fields" button when creating institutions.
  Disabled input fields when
  metadata is loaded either from locally stored data
  or dynamically fetched from ROR.
  or editing an institution with an existing ROR ID.
  Improved CSS and JavaScript for better responsiveness.

• Functionality

Users can type an institution name and see a suggested list with ROR data.
ROR ID validation implemented to prevent incorrect entries.
Improved error messages when an invalid ROR ID is entered.
Users can fetch institution metadata via ROR ID.
When creating an institution along with a project, the ROR ID is now saved properly.
Converted country codes to full country names for better readability.

• API

Added ror_id to the Institution API (Read/Write).
Updated API examples to include the new ror_id attribute.

I still think you should fetch all the metadata from ROR on the backend if a ror_id is present (especially since you are calling out to it to validate anyway).

for example:

before_validation :fetch_from_ror, if: -> { ror_id.present? && ror_id_changed? }

def fetch_from_ror
  response = Ror::Client.new.fetch_by_id(ror_id)
  if response[:error]
    errors.add(:ror_id, response[:error]) 
  else
    # ... assign attributes based on ROR response
  end
end

This would allow easy creation of institutions by just passing Institution.new(ror_id: "123abc")

Just one minor comment, but otherwise looks good
