Fix shared tour dates snippet: handle render_home and render_page modes

The snippet was checking `mode == 'render'` but both section files were
calling it with mode: 'render_home' and mode: 'render_page', so no rows
ever rendered. Now handles all three calling conventions:

  - render_home → gk-date-row prefix (home section CSS), no is-hidden
  - render_page → gk-date prefix, is-hidden on rows beyond visible_count
  - render      → legacy explicit mode (row_prefix + use_hidden_class params)
  - count       → returns upcoming date count only

Also adds backward compatibility for gk-dates-page.liquid which uses the
legacy mode: 'render' calling convention with explicit row_prefix param.

To add/edit dates, update the _gk_dates_raw capture block in the snippet.
Both sections update automatically.

-  GK Shared Tour Dates (Single Source of Truth)
-  - Snippet ONLY (no schema allowed)
-  - Renders rows for either:
-      row_prefix: 'gk-date'     (dates page styles)
-      row_prefix: 'gk-date-row' (home styles)
-  - Safe date filtering:
-      show_ts == 0 => keep it (prevents blank if date parse fails)
+  GK Shared Tour Dates — single source of truth
+  Snippets cannot contain {% schema %}.
+
+  Calling conventions supported:
+
+    render 'gk-tour-dates-shared', mode: 'render_home'
+      → outputs .gk-date-row markup (home section CSS)
+      → all rows output; JS hides beyond initial_visible via style.display
+
+    render 'gk-tour-dates-shared', mode: 'render_page', visible_count: <n>
+      → outputs .gk-date markup
+      → rows beyond visible_count get class "is-hidden" (CSS hides, JS manages)
+
+    render 'gk-tour-dates-shared', mode: 'render', row_prefix: 'gk-date', visible_count: <n>, use_hidden_class: true
+      → legacy explicit mode (same output as render_page when row_prefix='gk-date')
+
+    render 'gk-tour-dates-shared', mode: 'count'
+      → outputs only the integer count of upcoming dates
+
+  Safe date filter:
+    show_ts == 0 → Liquid can't parse the date string → keep it visible
+    show_ts  > 0 → hide the row if show is before today midnight UTC
