Improved permission checks

2025.1.0 introduced additional permission checks for accessions and inventories: it only returns records that belong to sites where the user has read access.

The UI correctly shows the data, but it does not fully consider user's permissions for rendering FAB buttons and actions. For example, the + to create an inventory is not displayed when the user doesn't have create permission on the default site, but has it for some of the sites.

Please update the permission checks so that FABs are displayed properly.

Site selection

On forms where the user selects the site (of inventory or accession), only those sites where user has create (for new records) or update (for existing records) should be listed. The best approach would be to upgrade the Site selector component so that it returns only those where the user has the relevant permission on the appropriate SecuredAction.
