Subject: feat: add Config with account, query, and sync parsing

Accounts use [account.work] rather than [account/work]: QSettings' INI
backend treats "/" as its own hierarchical group separator, so a literal
slash in a section header parses as a nested group and trips
QSettings::FormatError, silently breaking childGroups() enumeration. A
dot carries no such meaning and keeps the format flat.

Saved-query order is alphabetical (QSettings::childKeys() sorts), not
file order; documented in code and tests rather than left to a false
assumption.
