Migrate from the `reactstrap` `Form` component to `Form` from the `branded` package

Created by: valerybugakov

Problem statement

We want to get rid of Bootstrap styles. Since reactstrap depends on bootstrap styles, we need to extract component implementations that we use.

Success criteria

1. All Form imports from reactstrap are removed.
2. reactstrap Form usages migrated to the Form component defined in the branded package.

Implementation details

After migration, ensure that input validation works correctly on migrated pages.

Time estimate

• Split the work into multiple pull requests if the total diff is bigger than 450 lines of code.
