feat(theme): draw the app in the shard's chosen type families (M12 phase 3)

Phase 3 of M12 (docs/android/THEMING_AND_NAV.md §5.3) — the fonts third of the
admin's Appearance page, after phase 1's colors and phase 2's structure.

ShardTypeface.resolve(theme) maps the three font stacks onto three FontFamily
values and shardTypography(faces) draws the M5 type scale in them. Only the
family moves: every size, weight, line height and tracking is the M5 value, so
an unthemed instance reproduces the pre-M12 scale exactly. Resolution is pure,
so every assertion is a plain JVM test with no Compose rule.

Seven families are bundled beside the existing Cinzel (EB Garamond,
Merriweather, Playfair Display, IM Fell English, Inter, Work Sans,
Source Sans 3), taken verbatim from google/fonts the way M5 took Cinzel, each
with its SIL OFL licence under app/licenses/. Italics for the four families
client/index.html requests one for; the rest are skewed, as they were before.

Three things worth knowing:

1. The per-role font list is not the set of values a role can hold. The server
   validates admin-entered fonts against FONT_OPTIONS[role], but a preset's
   tokens are copied verbatim by resolveThemeTokens and never pass through it —
   `modern` publishes --display: 'Work Sans' and `fantasy` publishes
   --sans: 'EB Garamond', neither of which its own dropdown offers. The lookup
   is therefore one global map keyed by the lowercased first family name, and
   both preset cases are asserted by name so a per-role "tidy-up" fails loudly.
   Same trap phase 2 hit with --shadow-card, in a different token group.

2. The APK nearly tripled, and that was a decision, not a discovery. Measured
   unsigned release, R8 + resource shrink: 5,031,411 B (4.80 MiB) before,
   13,574,703 B (12.94 MiB) after — +8.15 MiB against a drafted estimate of
   1.5-2.5 MB. Merriweather alone is 6.08 MiB of that, because upstream ships
   it as a three-axis [opsz,wdth,wght] variable font that deflates only 31%.
   The org lead chose to bundle it verbatim with the cheaper options costed:
   Google's own static 400/700 builds would have held the app near 6.8 MiB,
   and dropping it near 6.2 MiB at the price of a serif option that silently
   does nothing on Android.

3. Typography implements equals — like phase 2's Shapes, unlike phase 1's
   ColorScheme, checked the same way in the material3 1.3.0 bytecode. AC-1's
   type half is one comparison against a verbatim copy of the pre-M12 scale
   held in the test.

No LocalShardTypeface: unlike the palette and the structure, MaterialTheme
carries the families completely, and the two composables that override
anything override the style rather than the family. Type.kt's `val Typography`
becoming a function is the whole migration — the three families were
referenced from that one file and nowhere else.

Tests: ShardTypefaceTest (15). 401 unit tests green (386 + 15), lintDebug and
assembleDebug clean. Not exercised on device — that is AC-5, in phase 8, where
IM Fell English's synthesised bold is the thing to look at.

- * Type families for the M5 shard-website design pass (docs/android/PLAN.md §M5).
+ * Every type family the app can draw with — the eight the admin's Appearance page
+ * can select between (THEMING_AND_NAV.md §5.3) plus the two system stacks its
+ * "shipped default" options resolve to.
  *
- * - [Cinzel] — the engraved serif display face used for headings, screen titles,
+ * All eight webfonts are **bundled**, not downloadable: the Play Store font
- *   and the top-bar title. Shipped as a single weight-axis **variable** font
+ * provider is the only downloadable-font source Compose ships with, so a
- *   (`res/font/cinzel_variable.ttf`, SIL OFL — see `app/licenses/Cinzel-OFL.txt`);
+ * de-Googled device would silently fall back and every text style would gain an
- *   the 500/600/700 instances the design uses are pinned via [FontVariation]
+ * async loading state. The binaries are taken verbatim from `google/fonts`, which
- *   (supported on API 26+, and our minSdk is 29).
+ * is how [Cinzel] arrived in M5; each carries its SIL OFL licence under
- * - [AppSerif] — the parchment body face. Android's platform serif is Noto Serif,
+ * `app/licenses/`, **never** under `res/font/` (aapt rejects a `.txt` there).
- *   which reads as the design's Georgia body copy without bundling another binary.
+ *
- * - [AppSans] — the label/meta/button face (the design's "Helvetica Neue" runs).
+ * A family reaches a text style through [ShardTypeface], which is what maps a
+ * shard's `--display` / `--serif` / `--sans` stacks onto these. The three
+ * declared *shipped* roles are [Cinzel] for the engraved display/headline/title
+ * block, [AppSerif] for parchment body copy, and [AppSans] for the letter-spaced
+ * label/meta/button block.
+ *
+ * ## Weights
+ *
+ * The type scale asks for four: 400 (body), 500 and 700 (labels), 600 (display).
+ * Every family here must supply all four, because a family is **not** confined to
+ * the role its dropdown lives in — the `modern` preset puts Work Sans in the
+ * display slot and the `fantasy` preset puts EB Garamond in the sans slot, both
+ * bypassing the server's per-role option list (see [ShardTypeface]). The variable
+ * families pin the four instances through [FontVariation] (API 26+; minSdk is 29).
+ *
+ * Two families are exceptions, both upstream facts rather than choices:
+ * - **[IMFellEnglish] has a single weight.** Its one 400 face answers all four
+ *   requests and Android synthesises the bold. The website's dropdown labels it
+ *   "(no bold weight)" for the same reason.
+ * - **[Cinzel] is left at the 500/600/700 it shipped with in M5.** It is the only
+ *   family the server offers in the display role alone, so nothing can ask it for
+ *   400; adding an instance would have edited M5's type for no reachable case.
+ *
+ * ## Italics
+ *
+ * Four families carry a true italic — the same four `client/index.html` requests
+ * one for. The rest are upright-only and Compose skews them, which is what the
+ * app already did for every family before this milestone and what the website
+ * does for its own upright-only faces. The app draws italic in two places.
