feat(web): Expenses and Audit keep a clear-filters control while rows are still showing (#679)

[mforce]

Closes #679.

The gap

clearFiltersButton appeared at exactly one call site: inside the zero-rows empty state. The control that clears filters only existed once the filters had already hidden everything.

Harmless while Expenses filtered by a month picker that was always set. #667 replaced it with a from/to range defaulting to the current farm month, so an unfiltered state now exists and the only ways to reach it were blanking two <input type="date"> controls segment by segment, or narrowing the range until the list emptied so the button appeared.

Audit was worse: four controls (entityType, action, from, to) plus a URL-borne entityId scope, and an empty state that is a bare <p className="muted"> by #655's classification — so no action at all, ever.

What shipped

A persistent control in the .filters row on both screens, keyed off whether anything is narrowing, present while rows are still listed.

Two product decisions, both the owner's (2026-09-05):

Question	Decision
What does "clear" mean on Expenses?	Restore the current-month default. Blanking would leave periodTotalLabel describing every expense ever recorded — the framing #667 deliberately declined to make the default
Where does Audit's control live?	The .filters row, not the empty state, so #655's classification of that empty state is untouched

One consequence I did not leave silent: with "clear" meaning restore the default, the empty state's old button was the only route to all-time, and it would now be a no-op when you are already sitting on the default with an empty month. So the empty state's action depends on where it is — narrowed past the default it clears back to the default; on the default it offers Show all time (expenses:showAllTimeButton, new key, all three locales). Different intent, different label, one button either way.

Two things worth a reviewer's attention

1. Audit clears all four filters in ONE URLSearchParams write. The PROTECTED comment on updateDateFilter is explicit that a handler writing several fields in one tick loses all but one in either setSearchParams form — it even names "a clear both dates button" as the latent case. A test pins the whole set, and the mutant that clears only action kills it.
2. entityId is deliberately NOT cleared. It is the scope the view was opened in (a row's Audit history link), not a filter the user set on this screen; dropping it would silently widen the page from one record to the whole farm. Asserted explicitly.

isNarrowed is left alone — it answers "which empty-state sentence applies" and excludes the scope axes on purpose. The control keys off a separate hasFilters that includes the entity type.

Verification

9 new tests. Mutation, baseline green both sides:

Mutant	Killed
Expenses clear blanks the range (the other meaning)	restores the current-month default…, offers the default-restoring clear…
Expenses persistent control removed (empty-state only again)	shows the clear control while rows are still listed + 2
Audit clears only one key (the partial-write regression)	clears all four filters in ONE write…, re-queries unfiltered after clearing
Audit control gated on rows being empty	shows the clear control beside the filters while rows are still listed + 2

One existing test changed rather than worked around: shows the truly-empty state once the filters are cleared encoded the old semantics (clear ⇒ blank ⇒ "No expenses recorded yet"). It now drives the same assertion through Show all time, which is the control that blanks the range under this decision.

Help page and all three locales updated in the same PR. Each locale's prose names the buttons by that locale's own labels — the rule #688/#696 records. GLOSSARY.md is untouched: no domain concept changed, only an affordance.

Full web suite 2513 passed / 114 files; npm run typecheck clean.

📝 Walkthrough

Walkthrough

Expenses now supports persistent filter clearing, current-month restoration, and all-time viewing. Audit now clears active filters while preserving record scope. Tests, localized Help content, and the product glossary document both flows.

Changes

Filter clearing and all-time views

Layer / File(s)	Summary
Expenses filter controls web/src/routes/ExpensesPage.tsx, web/src/routes/ExpensesPage.test.tsx, web/src/i18n/*.ts	Expenses restores the farm-month range, provides a separate “Show all time” action, and shows filter controls in filtered and empty states.
Audit filter controls web/src/routes/AuditPage.tsx, web/src/routes/AuditPage.test.tsx	Audit clears entity type, action, and date filters in one history update, preserves entityId, and reloads from offset zero.
Localized filter guidance web/src/routes/HelpPage.tsx, web/src/i18n/*.ts	Help content describes Expenses and Audit filter-clearing behavior in English, Spanish, and Filipino.
Product behavior documentation specs/product/GLOSSARY.md	The glossary documents expense date-filter behavior and audit filter clearing.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 0879e

The glossary documents the Expenses and Audit filter-clearing behavior without introducing an identified merge-readiness risk.

@coderabbitai review

Fixed in 61645ad and answered on the thread — the glossary finding was right, and my stated reason for skipping that file was wrong rather than merely incomplete. Worth a second look at the two new entries in specs/product/GLOSSARY.md: they are the only place the changed meaning of "Clear filters" on Expenses is written down for a reader who is not reading this diff.

[coderabbitai]

@mforce I will review PR #697 again. I will verify the two new specs/product/GLOSSARY.md entries and the related Expenses behavior.
