Add per-NPC event history and injection

[RANGROO]

What

• adds exact-NPC recent event history to the Stobe NPC editor
• keeps History aligned with the Stobe Adventure Log narrative event allow list
• adds an NPC-scoped event-type filter and recent-events table capped at the latest 100 rows
• places 📜 History last in the native Stobe editor tab order
• lets users inject ordinary inputtext events for NPCs outside the current scene
• supports optional additional NPC recipients and guarded shared-event deletion
• keeps the existing profile rollback viewer under the clearer Profile Versions label

Why

NPCs need to retain cross-scene handoffs and other roleplay context even when they are not currently together.

Stobe persists event recipients as JSON strings such as Herika|hand_801757824. The initial port only split pipe-delimited routing, so every native Stobe event missed the exact-NPC predicate and History appeared empty. This branch now parses Stobe's native JSON roster, removes runtime handle/status suffixes for exact matching and display, and retains legacy pipe-format compatibility.

Notes

• No schema migration or new event type. Injected rows use the existing inputtext event/context path.
• Existing save-load eventlog cleanup rolls these rows back when an older save predates them.
• History reuses the Adventure Log allow list and respects Stobe's spoken-delivery visibility.
• Exact JSON/pipe people-token matching avoids partial-name matches and ignores runtime |hand_... and audience-state suffixes.
• New injected rows use Stobe's native JSON people format.
• Deleting a shared event removes the single underlying row for every listed recipient.
• Stobe's native editor does not have a separate Background Life tab, so this preserves its existing tab model and adds History last.

Validation

• php -l lib/eventlog_helper.php
• php -l ui/api/stobe_npc_history.php
• php -l ui/adventurelog.php
• php -l ui/stobenpcs.php
• node --check ui/js/npc_event_history.js
• git diff --check
• focused helper checks for JSON/pipe recipient parsing, handle/status removal, exact matching, and partial-name rejection
• STOBE_DB_NAME=stobe_test php tests/ingress_people_regression.php
• STOBE_DB_NAME=stobe_test php tests/npc_history_snapshot_regression.php
• prior isolated stobe_test API round trip covered inject/read/filter/delete; this follow-up did not insert or delete a new event, so the JSON write-format change is source-, lint-, and CI-validated
• live API verification: Herika 100 rows, Plit 42 rows, and Getha 37 rows; Chapin correctly has no matching Adventure Log events
• browser editor verification: selected History tab rendered 100 rows for Herika with normalized recipient names and no horizontal overflow
• source inspection confirms the existing snapshot viewer is relabeled Profile Versions
• GitHub PHP Regression Tests workflow

Local Deployment

• deployed feature commit b5f62dc to /var/www/html/StobeServer in DwemerAI4Skyrim3
• preserved logs, sound cache, voices, portraits, item images, database state, profiles, and settings
• all six changed source files are deployed; the two recipient-matching fix files have matching SHA-256 hashes
• DB updater completed; Apache is active and the background processor is listening on port 12346
• deployed health page, NPC editor, and History API returned HTTP 200
• deployed History tab visually verified at desktop and 390px mobile widths with no horizontal overflow
