docs(dips): align DIPs casing and expansion with GIP-0081 (#1040)

The Direct Indexing Payments feature was named three different ways across docs, comments and
log strings — "DIPS" plus two conflicting long-forms — none matching the spec. This settles on
the GIP-0081 wording everywhere: "DIPs (Direct Indexing Payments)".
