Merge branch 'paste-buffer-large'

Buffers large pastes outside the textarea to prevent the
multi-second UI freeze that happens when megabytes of text get
committed to a <textarea> in one shot. Threshold 256 KB; first 50
lines + a banner render into the textarea, full content uploads
on Save.

+ * Save-time wrapper that delegates to codex's ProjectZomboidRedactor.
+ *
+ * Codex owns the canonical Project Zomboid PII patterns (Steam IDs, player
+ * names, world coordinates, plus IPv4 / IPv6 addresses with the v0.3.0
+ * release). This filter is the single point at which PZ-shaped PII is
+ * scrubbed on save; it replaces the previous IPv4Filter + IPv6Filter
+ * stage (whose IP-only matches left port suffixes intact) and adds the
+ * PZ-specific Steam ID, player-name, and coordinate redaction the generic
+ * filters never touched.
+ *
+ * Codex's IPv4 / IPv6 regexes are generic and apply to non-PZ pastes too;
+ * the PZ-specific regexes (Steam ID, player name, coords) mostly no-op on
+ * non-PZ content because they rely on PZ-specific anchors (`76561198`,
+ * the Steam-ID placeholder, `Combat:` / `Safety:` prefixes, `at` / `[`
+ * coord wrappers + trailing PvP verbs).
+ *
+ * Patterns are encapsulated inside the codex redactor and are not exposed
+ * to the client-side preview JS (`getData()` returns an empty array).
+ * Server-side redaction on save is the privacy guarantee; the preview is
+ * only a UX hint for users about what gets scrubbed.
