* Update lhs.bin and stepwise.bin to address #1417
* Not sure why GitHub Actions failing when Mac binaries only thing updated
* Fix base branch for GitHub Actions - patch
* Rerun defaults on Windows for failing GitHub Actions
* Fix indifference point macro description (#1788)
* Update PV PDF report templates (#1789)
* Fix Federal depreciation calculation in host_developer.xlsx (#1793)
Cell CashFlow!B398 incorrectly referred to $C$141 for federal custom depreciation allocation which caused divide by zero errors that propagated through workbook all the way to LCOE and NPV results.
This issue only affected Host Developer send-to-Excel with equations when 20-yr SL allocation (Inputs!C141) is set to zero.
Checked that all other FOM spreadsheets do not have this problem.
* UI message for battery grid charging with PBI (#1792)
Also trigger message on_change so message appears when you switch to Battery Dispatch pages.
* Marine Energy documentation revisions (#1790)
* Fix base branch in Github CI (#1779)
* fix base branch
* fix ref name
* set default branch to patch
* update test results
