refactor(i18n): route planning-pane labels through the catalog (T-467)

Migrate the user-facing strings in builtin.tickets, builtin.pql,
builtin.decisions, and builtin.problems (list/detail views, section headers,
filters, empty/loading/error states, type chips) to ClideSettings.i18n; extend
each extension's catalog. The detail/links tabs that had a bare title now wire
titleKey + i18nNamespace so the tab title resolves too. Context threaded into
the static label helpers. No en_US behaviour change (D-21).
