feat(ios): unblock device builds — dev team, push-entitlements env switch, mic/speech/background keys

DEVELOPMENT_TEAM=C738Z66SRW + target-level CODE_SIGN_IDENTITY (XcodeGen's
settingPreset injects the deprecated "iPhone Developer" at target level, so a
project-level override cannot win). Device build now BUILD SUCCEEDED on the free
personal team with an on-the-fly 7-day profile.

aps-environment lives in a new WebTerm.entitlements that is NOT attached by
default: CODE_SIGN_ENTITLEMENTS expands ${WEBTERM_PUSH_ENTITLEMENTS}, empty
unless set at xcodegen time. Proven both ways — attaching it on a free team
fails with "Personal development teams ... do not support the Push
Notifications capability".

Also pins SwiftTerm to exactVersion 1.13.0: the floating "from: 1.13.0" now
resolves to 1.15.0, whose new public hasActiveSelection collides with the local
one in TerminalScreen.swift:328 and broke every generate+build.
