fix(main): broaden anchor selector and show inline "can't anchor" note

findAnchorElement used a narrow selector ('button[name="train"],
a[href*="train"]') that often missed Torn's actual gym page DOM.
When it missed, applyMode fell through to dialog.setMode('free'),
snapping the dialog to the default bottom-right position — which the
user perceived as a 'bounce' when clicking 'Above training UI'.

Widen the selector to a priority-ordered candidate list and prefer the
form ancestor of any matched element. As a last-ditch, look for a form
inside the gym panel. This covers more of Torn's gym-page variations.

When the anchor selector still misses, do NOT snap to the default free
position. Instead, keep the dialog where it is, set anchorError on the
state, and let the dialog render an inline note so the user gets
visible feedback explaining what happened.
