A balance refresh that returns now draws the balances on AddressDetail or
AddressToken again when that screen is up, not only the wallet list. Their
transaction lists are left alone.
Every add path on AddToken and SettingsAddToken tracks a token through
trackToken(), which gives the tracked record `balanceNotFetched: true`. While
the field is set, the token's line reads `quantity unknown` instead of 0.0000.
refreshBalances() now resolves with the tracked tokens whose balance it read
at every address. The popup's refresh deletes the field from those tokens in
the stored record and leaves the rest of the stored list as it is. Removing
the token removes the field, and each network keeps its own records.
Model: opus-5-5
When the contract lookup on AddToken answered, the popup went to AddressDetail even after the user had opened another screen. It now goes there only while AddToken shows and has not been opened again since Add was pressed; AddToken counts its openings as Send does. The token is still added as before unless the network changed. An answer, found or failed, from an earlier opening leaves the screen and the status line alone, so a later lookup's "Looking up token..." stays.
Judgement call: a user who went Back to AddressDetail during the lookup sees the new token once that screen is drawn again.
