Fix extensibility docs: add sfcc. prefix to all target IDs, add missing targets (#25)

Cross-referenced storefront-next implementation with commerce-apps docs and
found all target IDs were missing the required `sfcc.` prefix. Also added ~60
missing target IDs (cart, mini cart, PLP, product card, my account, user
registration, email signup, order confirmation, global) and marked WRAPPER
vs INSERTION target types.
