fix(scrapers): bad credentials detection and error message cleanup (#367)

Browse source 
## Problem

Wrong credentials produced garbled error messages (`"login failed: Login
failed: bad_credentials"`) and stale credentials remained cached after
failure, causing silent re-use on the next invocation.

## Solution

Standardize all scrapers to emit `"bad_credentials"` as a plain error
code, mapped to a human-readable string via `LOGIN_ERRORS` in
`constants.lua`. Fix `credentials.lua` to clear cached credentials on
failure in both the fresh-prompt and re-prompt paths. For AtCoder and
Codeforces, replace `wait_for_url` with `wait_for_function` to detect
the login error element immediately rather than sitting the full 10s
navigation timeout. Add "Remember me" checkbox on Codeforces login.
