fix(panel): recognize this fork's -awg.N tags in version comparison

internal/config/version was never bumped past 3.5.0 when v3.5.0-awg.1 was
tagged, so a freshly-updated panel kept reporting its own version as the
plain upstream base. On top of that, parseVersionParts (Go and its
TypeScript mirror) required exactly 3 dot-separated numeric parts, so it
rejected the -awg.N suffix entirely and fell back to a raw string
inequality that reports "update available" any time the strings merely
differ -- which they always do here, even when already on the latest tag.

Bump the embedded version to 3.5.0-awg.1 and extend both parsers to treat
"-awg.N" as an optional 4th, lower-priority component (defaulting to 0 for
a plain tag), so e.g. 3.5.0-awg.2 > 3.5.0-awg.1 > 3.5.0 and a matching tag
compares equal instead of always looking outdated.
