* Bump version to next iteration after v0.7.1-rc.1.1 release
* fix: correct last_6_months period to show exactly 6 months
Default start date was snapping to beginning_of_month 6 months ago,
producing a 7-month window (e.g. Nov 1 – May 31). Fix computes the
start as (end_of_month + 1 day - 6 months).beginning_of_month so the
default window is consistent with the navigation arrows and Today button.
* improved test
