A page that had not yet taken another page's network switch could lose tracked tokens. - Its save of an added or removed token wrote its own network's list as the new network's list. saveState() now keeps the stored list. It merges the add or removal into the stored list of the page's own network in networkTrackedTokens. - Its own switch in Settings wrote its old lists of tracked tokens per network over the stored ones. onChainSwitch() now first takes the stored switch with takeStoredNetwork(), and then switches from there. - takeStoredNetwork() replaced the page's tracked tokens with the stored ones. It now keeps the page's unsaved change in the list of the page's network. This also fixes #706. Model: opus-5-5
