fix(i18n): drop dot and dash separators from visible strings

Every bundle value that chained facts with " · " now reads as a phrase,
a comma list or a parenthesis, in all seven locales, and the em-dash
separators in the day, documents, correlation, sharing, environment,
vaccination and Apple Health import strings become sentences or clauses.

The day view's running list names the record first, with the dose in
the name and a life event's category as a chip, and puts a quiet day
count below: "Day 4, since 31 December" instead of a dot chain. Document
meta, location periods, vaccination rows and mood crosstab rows drop
their composed dots too.

A guard walks every bundle and fails on any " · " outside a reasoned
allowlist, and on an allowlist entry that no longer needs its place.
