fix(fusion_repairs): admin sees app + add placeholder icon

Two related issues that hid the Fusion Repairs app from the Apps menu
for admin users:

1. Custom security groups don't auto-include admin

   The Repairs User / Dispatcher / Manager groups are new custom groups.
   Having base.group_user or base.group_system on its own does NOT grant
   membership in custom child groups - implied chains only flow one way
   (child -> parent). Admin therefore had no Repairs groups, so the
   top-level "Fusion Repairs" menu (gated on group_fusion_repairs_user)
   was hidden from them.

   Fix: extend base.group_system with implied_ids that include
   group_fusion_repairs_manager. Manager already implies Dispatcher
   implies User, so admin (= base.group_system) now automatically gets
   the whole chain on install / upgrade with no manual user editing.

   Verified via odoo-shell:
     admin.has_group('fusion_repairs.group_fusion_repairs_user')       == True
     admin.has_group('fusion_repairs.group_fusion_repairs_dispatcher') == True
     admin.has_group('fusion_repairs.group_fusion_repairs_manager')    == True
     menu_fusion_repairs_root._filter_visible_menus()                 == ir.ui.menu(2735,)

2. Missing static/description/icon.png

   The manifest referenced fusion_repairs,static/description/icon.png
   via web_icon on the top-level menu but the file did not exist. Odoo
   handles missing icons gracefully but the apps list ends up rendering
   without a tile graphic. Copied fusion_tasks/static/description/icon.png
   as a placeholder; replace with a custom asset whenever desired.

   Verified: /fusion_repairs/static/description/icon.png returns
   HTTP 200 with 43989 bytes after restart.

Bumped manifest version to 19.0.1.0.1 to bust the asset bundle hash so
clients pick up the new icon without a manual cache clear.
