fix(splashboard): redesign project dashboards + dedup contributors (#523)

The bundled project dashboard was rendering as a stack of look-alike rounded
boxes with a broken `font = "standard"` figlet banner, and the Top
Contributors bar chart was showing the same user twice ("23 | 23 ola | ola")
because four git identities had never been collapsed.

Bundled `home/shell/splashboard/project.dashboard.toml` rewrite:
  - Banner switches to `font = "ansi_shadow"` with `color = "panel_title"`
  - 3-pill status badge strip (git_age / git_status / git_stash_count)
    replaces the old Status + Age 2-column row
  - Full-width 12-month commit heatmap (border = "thick") as the centerpiece
  - `chart_pie` for LOC by language (vs yet another bar chart)
  - `list_ranking` of largest files alongside the pie
  - `list_timeline` for recent commits with bullets and relative time column
  - Horizontal `chart_bar` for contributors at 2/5 width so names fit
  - Mixed border hierarchy (thick → rounded → top → rounded) for rhythm

Per-repo `.splashboard/dashboard.toml` for this nixos repo:
  - Same hero band + badge strip vocabulary
  - GitHub-mirrored 12-month contributions heatmap as the centerpiece
  - `github_languages` rendered as `chart_pie` (vs the previous bar chart)
  - New `code_largest_files` ranking with medal glyphs (🥇🥈🥉)
  - `github_recent_releases` as `list_timeline` (date column + bullet)
  - `github_contributors_monthly` as `list_ranking` with medals — different
    vocabulary from the bundled default's bar chart

`home/shell/splashboard/home.dashboard.toml` minor tune-up: hero date
recolored `panel_title` → `accent` so home and project have distinct
identities; fortune footer gets `border = "top"` for a closing seam.

`.mailmap` (new) collapses four committer identities (olafkfreund /
Olaf K-Freund / Olaf Krasicki-Freund across three emails) into one
canonical `Olaf Krasicki-Freund <olaf@freundcloud.com>`. `git shortlog
-sne` now reports 1908 commits under one author; `git_contributors`
honors this via gix, so the duplicate bars in the chart collapse to a
single full-height bar.

`_typos.toml`: add `ratatui` to the allowlist — it's the actual Rust
TUI library splashboard is built on, not a misspelling of `ratatouille`.

Verification:
  - All three TOML files parse via python tomllib
  - Every widget's fetcher / render shape combo verified against
    `splashboard catalog renderer`
  - `just test-host p620` succeeds; new home-manager-files derivation
    contains the new TOMLs
