Subject: [PATCH] Add filtering for tradeable seeds (#4111)

* feat: Add filtering for tradeable seeds

This change introduces a new feature to filter seeds based on their tradeability.

- Adds a link on the homepage to view all tradeable seeds.
- Modifies the seeds controller to support filtering by `tradeable_to`, allowing multiple values to be selected.
- Adds links to the seeds index page to filter by the various `tradeable_to` values.

* Update index.html.haml
