Apply the compare report's "result analysis" presentation to Trends -> By
category (table view). Categories are grouped into Income -> Expenses ->
Transfers sections with per-month and total subtotals; the old mixed "Total"
row (which summed absolute magnitudes into a meaningless figure) is replaced by
a Net result row per month (income - expenses + transfers) plus a Result before
transfers row shown only when transfers exist, both coloured by sign. Category
cells stay neutral levels.
- reportService.getCategoryOverTime: project COALESCE(c.type,'expense') in both
SELECTs and return an additive `types` map (built from the top-N rows, like
`colors`). Dashboard widget and CategoryOverTimeChart are untouched.
- shared types: add `types` to CategoryOverTimeData.
- new pure module overTimeResults.ts (computeOverTimeResults) with unit tests -
the per-month result reducer, mirroring the compare's pure Totals helper.
- i18n: add reports.compare.resultNet / resultBeforeTransfers (FR+EN); reuse the
existing sections.* and total* keys.
- .gitignore: anchor the autopilot `reports/` rule to `/reports/` so it no
longer swallows new files under src/components/reports/.
Section order is income-first (Revenus -> Depenses -> Transferts), per the
issue; the existing COMPARE_TYPE_ORDER is expense-first, so a local
OVER_TIME_TYPE_ORDER is used rather than reusing it.
Resolves#256

- New useReportsPeriod hook reads/writes period via ?from=&to=&period= URL params,
default civil year, pure resolver exported for tests
- New per-domain hooks: useHighlights, useTrends, useCompare, useCategoryZoom
(stubs wired to useReportsPeriod, to be fleshed out in #71-#74)
- Rewire legacy useReports to consume useReportsPeriod; keep backward-compat
state shape (period/customDateFrom/customDateTo) so /reports tabs keep working
- Mark useReports @deprecated pending removal in #76
- Tests: 7 new cases covering resolveReportsPeriod defaults, bookmarks,
invalid inputs, preset resolution
Fixes#70
