fix(#48): find config.yaml from server/ and stop diagnostics looking like errors

The startup log proved config.yaml was not being found during migrate.
Lookup covered the working directory and the executable's directory, but
the server runs from server/ while config.yaml sits at the repository
root — so it was found only when a launcher happened to export
GOAUTO_CONFIG. Anyone running `go run .` by hand got no local config at
all. Search the parent directory too, with the working directory still
winning.

The diagnostics also wrote to stderr, and the launcher pipes the server
through `2>&1 | Tee-Object`, which turns every stderr write into a
PowerShell NativeCommandError. The informational line I added to make
this debuggable was itself rendering as a red error block. They go to
stdout now.

Launchers set the console to UTF-8: Go writes UTF-8 while the console
decodes as the ANSI code page, which turned every Chinese log line into
mojibake.

Verified by running the built binary from server/ with no GOAUTO_CONFIG
set: it loads ../config.yaml and the lines survive 2>/dev/null.

Not verified: the two PowerShell edits, which need a Windows run.
