`TransactionId` had no `TextValue`, which blocked the operation layer: it is a
core type, so epiphany-ops cannot implement a core trait for it.
The fix is not the missing line. `bytes_text_value!` was a hand-maintained list of
thirty ids sitting parallel to the `graph_id!` invocations that declare them --
the same shape that has cost this project four bugs -- and `TransactionId`'s
absence was that latent bug already biting. `graph_id!` now generates the
`TextValue` impl beside the id itself: every graph id is a byte-string leaf by
definition, so the list that declares them is the list that projects them.
`bytes_text_value!` keeps only the leaves that are genuinely not graph ids --
`ContentHash`, `TypedObjectId`, `ReplicaId`, `OperationId` -- shrinking from
thirty entries to four. A graph id added tomorrow gets its projection for free
and cannot be forgotten.
