fix(nav): a distinct icon per table and a storage app icon

Every db_perf_ table used the speed icon, which repeats in the nav and
clashes with web performance (kof22's nav icon uniqueness check).

 ## [Unreleased]
 
 ### Fixed
+- Each table has its own icon (the app icon is now `storage`), so nav entries are distinguishable and do not repeat icons used elsewhere.
 - Home tables keep at most four columns with plain headers (readable at every width): secondary facts such as calls and mean time, the session's query text, and a unit's kind and top table move into a second line of the first cell.
