Commit Message

fix: add unique index on subscriptions to prevent duplicate entries

- Uses disable_ddl_transaction! (https://api.rubyonrails.org/classes/ActiveRecord/Migration.html#method-i-disable_ddl_transaction-21)
- Uses algorithm: :concurrently (https://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html#method-i-add_index)
- Removes 31 duplicate subscriptions from production database
- Prevents race conditions from causing duplicate entries in future

Why (member_id, group_id) not (member_id, chapter_id)?
- Index on (member_id, group_id) allows a member to be both student AND coach in the same chapter
- Each chapter has separate "Students" and "Coaches" groups - different group_id values
- This index prevents duplicate subscriptions to the SAME group (the race condition bug)
- But allows valid dual membership: member can subscribe to group_id=1 (Students) AND group_id=2 (Coaches)
