feat: copy connection URL from connection card menu (#22)

Add 'Copy connection URL' (with password, fetched from the OS keychain on
demand) and 'Copy connection URL (no password)' to the connection card kebab
menu. Builds postgresql://, mysql://, sqlite://, redis:// strings with
percent-encoded credentials and the PG sslmode appended. Bump to v0.7.10.
