fix(backup): carry the mood tags an account made, so its own file can be restored

The restore resolves a mood entry's rated factors by key and asks only for the
seeded catalogue. A tag the user created is not in it, so the lookup came up
short and the whole restore threw 'Unknown mood factor keys'. The file was
complete; it simply could not be read back.

That is the same cause as the cycle symptoms two commits ago, with the
opposite ending. There, an unresolvable key was filtered out and the loss was
silent. Here it stopped everything. One shape of missing definition, two
answers, neither of them the right one.

The account's own tag definitions travel now, get written before the factors
resolve, and the lookup accepts the seeded catalogue or the owner's own. The
seeded rows stay out of the file for the same reason as before: a restore must
not rewrite another instance's reference data.

Four more test mocks needed the new delegate, which is again the compiler and
the suite naming the call sites rather than me hunting for them.
