Task IDs Fixed for Projects with Special Characters

AI coworker can now create tasks correctly in projects with special characters in their prefix, such as CC&V or R&D.

Bug Fixes

AI coworker can now create tasks in projects whose prefix contains special characters (e.g., CC&V, R&D) — previously all tasks in such projects received the same ID, causing most of them to fail
Improved error logging for task creation failures so errors are no longer silently swallowed

Projects with prefixes containing special characters like & (e.g., CC&V for "Child Custody & Visitation", or R&D) previously caused the AI coworker to fail when creating multiple tasks at once. The underlying ID counter query used a regex that only matched letters, so every task was assigned the same ID and all but the first were rejected.

Sequential task IDs now work correctly regardless of what characters appear in the project prefix.
