perf(ios): resolve text fields via typed queries, not full-tree enumeration

textInputAt used app.descendants(.any).allElementsBoundByIndex (snapshots EVERY
element) to find the text input at a point. fill drove this repeatedly: once it has
coordinates, resolveTextEntryElement re-runs textInputAt on every verify/repair poll
iteration whenever the focused-field reference goes stale (e.g. the Settings search
bar repositioning bottom->top), so the full-tree enum dominated fill latency.

Query the text-input element types directly (app.textFields/secureTextFields/
searchFields/textViews) instead. Same matches, but XCUITest resolves typed queries
without snapshotting the whole tree. Measured (iPhone 17 sim, warm runner): fill 25
chars ~14.5s -> ~4.5s (3.2x), 6/6 exact. Same primitive #632 killed for get text.
