report-fetch-request-ui (#7)

## MR: Fetch Request Pipeline, Report Snapshots, and Admin Filtering

### Summary
Adds fetch request pipeline UI, report snapshot manager, snapshot selector on dashboard, and client-side in-memory filtering for the admin panel. Also overhauls the Home page with feature cards and adds navigation links.

### Changes

**New Pages**
- `/fetch-requests` — Upload bank statements (two-step: upload file, then configure source) or configure email ingestion. Table shows fingerprint (with copy), source type, account, status (color-coded chip), and created date.
- `/reports` — Generate cached report snapshots with filters (ignore self, date range, amount range). Table shows snapshot ID (with copy), creation time, and query summary chips.

**Dashboard**
- Snapshot selector autocomplete dropdown (formatted "Snapshot from {date}"), passes `snapshot_id` to `useReport`
- Styled to match other filter controls (caption above, auto-height)

**Admin — In-Memory Filtering**
- `FilterBar` component: collapsible, Dashboard-style column layout with caption + autocomplete/range/date inputs per filterable field
- `FilterAutocomplete` component: multi-select, free solo, checkmark ticks, selected-first sort frozen while dropdown open (prevents scroll reset)
- `applyClientFilters` in `ResourceView`: handles number range, datetime range, array (object/string elements), non-relation objects, boolean, primitive exact match
- Config-driven via `filterOptions: { mode: "client", fields: [...] }` in `openapi-config.ts`
- Mobile view: each filter takes full width (`flex: "0 0 100%"`), no horizontal squeeze
- `rowCount` omitted in client pagination mode (suppresses MUI X warning)

**Navigation & Home**
- Header nav links: Dashboard, Fetch, Reports
- Home page redesign: gradient hero, "Import Data" CTA, 4 feature cards (Dashboard, Fetch Requests, Report Snapshots, Admin) with accent-colored hover effects

**React-OpenAPI Library**
- `filterOptions` (mode + fields) on `ResourceOverride` and `ResourceConfig` types
- `EnhancedTable` mobile pagination (10 per page with Prev/Next, prevents browser hang with 10000 records)
- `useResource` accepts `filterOptions` from loader

**Misc**
- `public/favicon.png` added, proper `image/png` type in index.html
- 24 files changed, ~1541 insertions, ~100 deletions
