Refactor: Replace inline style objects with makeStyles classes

Moved all static layout properties (display, gap, margin, padding, colour)
from inline style props to makeStyles classes in:

- MapBansTable.tsx: Pagination row flexbox layout
- JailDetailPage.tsx: Link styling for textDecoration
- HistoryPage.tsx: Summary text styling
- IpDetailView.tsx: Loading container and text formatting

Kept inline styles only for genuinely dynamic values:
- WorldMap.tsx: Tooltip position (follows mouse)
- TopCountriesPieChart.tsx: Legend color (from recharts data)
- TopCountriesBarChart.tsx: Chart height (derives from data length)

This change improves performance by leveraging Griffel's atomic CSS cache
and ensures consistency with the established Fluent UI pattern.

Updated Docs/Web-Development.md with explicit rule: inline styles only
for runtime-dynamic values, all static properties go in makeStyles.

-### T-19 · Move `DashboardFilterProvider` — page-scoped provider in wrong directory
-
-**Where found:** `frontend/src/providers/DashboardFilterProvider.tsx` — instantiated only inside `DashboardPage.tsx`
-
-**Why this is needed:** The `providers/` directory implies app-wide providers (alongside `AuthProvider`, `ThemeProvider`, `TimezoneProvider`). `DashboardFilterProvider` wraps only `DashboardPageContent` and is not used anywhere else. Its placement implies reuse that doesn't exist, misleading future contributors about its scope.
-
-**Goal:** Co-located with its only consumer.
-
-**What to do:**
-1. Move `DashboardFilterProvider.tsx` to `frontend/src/pages/` (alongside `DashboardPage.tsx`) or to `frontend/src/pages/dashboard/` if the page is split into a subdirectory.
-2. Update imports in `DashboardPage.tsx` and any tests.
-
-**Possible traps and issues:** Only `DashboardPage.tsx` imports it — confirm with grep before moving.
-
-**Docs changes needed:** `Docs/Web-Development.md` — document what belongs in `providers/` (app-wide) vs co-located.

 ### T-20 · Replace inline `style={{}}` objects with `makeStyles` classes

 - Co-locate styles in the same file as the component they belong to, defined above the component function.
 - Use `mergeClasses` when combining multiple style sets conditionally.
 - Reference Fluent **design tokens** (`tokens.colorBrandBackground`, `tokens.fontSizeBase300`, etc.) instead of hard-coded values — this ensures consistency and automatic theme support.
+- **Inline styles are only allowed for genuinely dynamic values** (e.g., tooltip position calculated from mouse position, or height derived from data count). All static layout properties (`display`, `gap`, `margin`, `padding`, colour) must go in `makeStyles`.
