Replaces the survival-specific preset list with general-purpose starter
tags (recipes, diy, health, technology, finance, travel, hobbies,
reference, survival, energy) so the Knowledge Base reads well for
home-lab/reference use, not just prepping.
Adds sanitizeCollectionName() (trim, lowercase, length cap) applied on
every write path server-side, and a dependency-free CollectionCombobox
component replacing the plain <select> + window.prompt pattern for
tagging — autocompletes against presets + tags already in use, with a
'+ Create' option for anything new.
