Replace inline Save/Discard/Reset buttons with sticky glass-bubble pills
that float at the bottom of scrollable modal content. Make SpaceSettings
tab sidebar sticky with glass material. Convert RoleEditView "Back to
roles" into a sticky glass pill at the top. UserSettings Log Out + Save
always visible in a glass pill with separator. Also includes floating
position hook and popover/tooltip improvements from prior work.
Restructure SpaceSettings modal from 778-line monolith into thin
orchestrator with extracted panel components. Add full role CRUD with
permission editor (create, edit name/color/permissions, delete).
Backend: expose role permissions in GET response, accept permissions
in POST/PATCH role endpoints with BigInt validation, broadcast
pushReadyPayload to all space members on role mutations.
