Remove cross-domain template dependencies from shared infrastructure

- macros/search.html: shared search input macros (mobile + desktop)
- macros/cart_icon.html: shared cart icon/badge macro (count param, no DB)
- macros/layout.html: inline hamburger icon, use shared search macro
- _oob.html: use cart_mini_html fragment slot instead of cart template import
- db/session.py: guard teardown rollback against committed/dead sessions
