Update quoted replies & new quotes features

[corinagum]

• Remove withReplyToId(): replyToId body property has no effect on threading (APX only uses it for encryption)
• Add QuotedReplyEntity type with nested quotedReply data object (messageId required, senderId/senderName/preview/time/isReplyDeleted/validatedMessageReference optional)
• Add getQuotedMessages() on MessageActivity to read inbound quoted reply entities
• Add addQuotedReply(messageId, response?) builder on MessageActivity for constructing outbound quotes (build order = reading order)
• Update reply() to stamp quotedReply entity + <quoted messageId="..."/> placeholder instead of blockquote HTML; remove replyToId assignment
• Add quoteReply(messageId, activity) on ActivityContext for quoting arbitrary messages
• Mark all quoted reply types and methods as @experimental
• Fix bug in ActivityContext constructor where Object.assign(this, rest) ran before MessageActivity.from().toInterface(), causing interface methods (getQuotedMessages, stripMentionsText, isRecipientMentioned, getAccountMention) to be missing on context.activity. Added regression test.
• Add quoted-replies example exercising all APIs

Pull request overview

This PR updates the SDK’s reply/quote behavior to use Teams “quoted replies” (entity + <quoted .../> placeholder) instead of replyToId/blockquote HTML, adds first-class quoted-reply types/APIs, fixes an ActivityContext constructor enrichment bug, and introduces an example app to exercise the new functionality.

Changes:

• Add QuotedReplyEntity/QuotedReplyData, plumb into Entity union, and add MessageActivity.getQuotedMessages() + addQuotedReply().
• Update ActivityContext.reply() to stamp quoted-reply metadata + placeholder, and add ActivityContext.quoteReply(messageId, ...).
• Fix ActivityContext constructor ordering bug (enrichment before Object.assign) and add regression tests + a new quoted-replies example.

lg2m. Lmk if we change between quoteReply and quote. Both sound ok to me!
