Rework ShipStats page

[floribe2000]

• - collapsed subsections by default
• - move settings link to regular navigation
• - move secondary range into main secondary expander
• - Remove detection from subs at maximum depth from concealment data container
• - swap positions of concealment and maneuverability datacontainer
• - consider adding icon for shell type, alternatively: prefix shell name with shell type
• - share expander state between tabs within one session (enabled by default, maybe optional)
• - show "add new ship" when removing last ship on ships page (evaluate embedding selector in page vs. opening popup as usual)
• - check if tabs header can be made sticky
