feat: align save-time redaction with codex v0.3.0 ProjectZomboidRedactor

Bumps the codex constraint from ^0.2.0 to ^0.3.0 to pull the PZ-B42
parser fix and the IP-redaction passes added in the codex v0.3.0
release. Wires codex's ProjectZomboidRedactor into the save-time
Filter chain via a thin ProjectZomboidRedactorFilter wrapper, and
removes the now-redundant IPv4Filter / IPv6Filter chain entries:

- Codex's IPv4 / IPv6 redaction is generic-applicable (not PZ-only)
  and superior to the prior in-tree filters because it consumes the
  port suffix together with the address; previously only the IP was
  scrubbed, leaving e.g. ":27015" visible.
- Codex additionally redacts PZ-specific PII the prior filters never
  touched (Steam IDs, player names, world coordinates).
- The IPv4Filter and IPv6Filter source files are retained on disk
  for easy restore from history if a future paste type proves
  unsuitable for codex-driven IP scrubbing.

UsernameFilter (OS-path username scrubbing — different concern from
PZ player names) and AccessTokenFilter remain untouched.

+ * 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.
