fix(deps): update module google.golang.org/appengine to v2

fix(drivers/189pc): align login with the official PC client (#3105 )
QR code scans were authorized on the phone but the storage stayed stuck on the QR page, and token-only setups failed with "params is null". The driver used appId 8025431004 while the official PC client uses 9317140619. Tokens, sessions and QR sessions are all scoped to an appId, so the mismatch meant the QR poll never saw status:0 and an accessToken could not be exchanged for a sessionSecret. - Use appId 9317140619 and version 7.2.4.0. QR state polling uses clientType=1; password login keeps 10020. - Send the QR poll parameters the official client sends (cb_SaveName, isOauth2, state, user-finger header, logbox Referer) and poll locally instead of only checking once per save. - Parse lt/reqId from the logbox redirect and paramId from appConf.do. The new login page no longer embeds them as inline variables; the old inline format is still supported. - Implement the -133 second device verification via sendSmsCodeForSecondAuth/submitForSecondAuth. That endpoint has no dedicated SMS field: the code goes into epd, encrypted with the same public key used for the password. Persist the DEVICEID cookie so the verification only happens once. - Detect refreshToken.do failures. It reports them as HTTP 200 with a result field, so SetError never fired and a failed refresh was treated as success, surfacing later as a misleading "params is null". - username/password are no longer required, so token-only storages save without placeholders. clientSn/jgOpenId are optional and only sent when configured; user-finger is generated once per storage. - Return named errors instead of panicking when the login page changes shape.

naiy_	4c39bbe9c2	fix(drivers/189pc): align login with the official PC client (#3105 ) QR code scans were authorized on the phone but the storage stayed stuck on the QR page, and token-only setups failed with "params is null". The driver used appId 8025431004 while the official PC client uses 9317140619. Tokens, sessions and QR sessions are all scoped to an appId, so the mismatch meant the QR poll never saw status:0 and an accessToken could not be exchanged for a sessionSecret. - Use appId 9317140619 and version 7.2.4.0. QR state polling uses clientType=1; password login keeps 10020. - Send the QR poll parameters the official client sends (cb_SaveName, isOauth2, state, user-finger header, logbox Referer) and poll locally instead of only checking once per save. - Parse lt/reqId from the logbox redirect and paramId from appConf.do. The new login page no longer embeds them as inline variables; the old inline format is still supported. - Implement the -133 second device verification via sendSmsCodeForSecondAuth/submitForSecondAuth. That endpoint has no dedicated SMS field: the code goes into epd, encrypted with the same public key used for the password. Persist the DEVICEID cookie so the verification only happens once. - Detect refreshToken.do failures. It reports them as HTTP 200 with a result field, so SetError never fired and a failed refresh was treated as success, surfacing later as a misleading "params is null". - username/password are no longer required, so token-only storages save without placeholders. clientSn/jgOpenId are optional and only sent when configured; user-finger is generated once per storage. - Return named errors instead of panicking when the login page changes shape.

帅丘	e1d88b071f	fix(drivers/lanzou): support new /fn download page structure (#3157 ) Lanzou recently changed the file share page: download params moved into an iframe (/fn?<token>) inner page, and the download API is now an absolute URL (https://apifile.woozooo.com/ajaxfile.php?file=N) with new sign params (wp_sign/ajaxdata, action=downprocess). The old findFileIDReg ('/ajaxm.php?file=N' relative path) no longer matches, causing 'failed link: failed get link: not find file id'.
