LF-5169: Previously Applied Filters Persist on Animals Page After Switching Farms

[litefarm-pr-bot]

Description

When a user applies filters on the Animals page and then switches to a different farm, the filter state was stored in tempStateReducer.filterReducer (Redux). The root reducer only clears farmStateReducer on farm switch, and clearOldFarmStateSaga — which handles cleanup during the farm-switch saga flow — did not include a reset for the Animals filter. Because the filter state lives outside farmStateReducer, it survived the farm transition intact.

The fix adds resetAnimalsFilter() to clearOldFarmStateSaga in containers/saga.js, alongside the existing resetTasks() and resetDateRange() calls. This ensures Animal filters are cleared at the same point in the farm-switch flow as other domain-specific state.

Any new domain-specific filter state stored in tempStateReducer should similarly be reset in clearOldFarmStateSaga rather than relying on the root reducer's SWITCH_FARMS handling, which only covers farmStateReducer.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Passes test case
• UI components visually reviewed on desktop view
• UI components visually reviewed on mobile view
• Other (please explain)

Logic change reviewed in source code. No local frontend running; visual review not performed. The fix is a single yield put(resetAnimalsFilter()) call in an existing saga, consistent with how resetTasks() is handled in the same function.
