Polish layout of security system views

[glebfox]

Feature Description

Security system views have ugly layout, e.g.

ResourceRoleModelDetailView and RowLevelRoleModelDetailView

Action buttons are go beyond view boundaries if not enough space

This can be fixed by making actions box fixed position, e.g.:

RoleAssignmentView

Tables don't occupy the full height

and can be collapsed for no reason

Layouts of security system views have been changed, so may lead to problems if someone extended them.

For QA: Check that the following views are still usable:

• ResourceRoleModelDetailView - Security > Resource roles, create/edit a role
• RowLevelRoleModelDetailView - Security > Row-level roles, create/edit a role
• RoleAssignmentView - Users, select a user > Role assignments
