Keep a research project to the character who started it - #15

Conversation
Stations were owned by the account, so any character on it could open a project and spend its own focus there. A station now records the starting character, and other characters get the "in use" message and cannot act through an already open menu. Stations saved before this belong to the next character to open them. Part of TF-Minecraft/RPCharacters#89. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Require an active character before starting a project.
The lectern path checks only the station permission before calling startProject. If no active character exists, startProject saves the station without an ownerCharacterId. A later character can then claim it. Reject the start before consuming the item or saving the station when no active character exists. Keep the existing claim behaviour for legacy stations without an owner.

A research station belonged to the Minecraft account, not to a character. Focus is kept per character, so a player could start a project, switch to another character, open the same lectern and spend that character's focus on it, then repeat with every character on the account. Several characters could pool their focus into one project.
A station now records the character who started its project, and the file under
plugins/Research/data/stations/keeps it asowner_character_id. Another character on the same account gets the usual "in use" message when it clicks the lectern, and a menu that was already open stops responding after a switch, so no focus is spent and no experiment is run. Stations saved before this change have no character recorded; the next character to open one becomes its owner. No configuration or message changes are needed.Unit tests cover a second character being refused at the lectern and through an open menu, the starting character carrying on as before, older stations being claimed on first open, the character being recorded at start, and the new field surviving a save and load.
