Title: [Bug] Scheduled messages shift to next day at exact hour & UI corruption after enabling read receipts (iOS)

Summary

Two critical issues introduced in recent Telegram updates are affecting core messaging functionality:

1. Scheduled messages incorrectly shift to the next day when set at exact hours
2. UI corruption occurs after enabling read receipts

Both issues are reproducible and significantly impact usability.

Issue 1: Scheduled Message Date Shift

Description:
When scheduling a message at an exact hour (e.g., 20:00), the system automatically shifts the scheduled date to the next day.

Example:

• User selects: "Today at 20:00"
• Actual result: Automatically changed to "Tomorrow at 20:00"

Key Condition:

• Happens consistently when minutes are set to 00
• Does NOT occur when minutes are non-zero (e.g., 20:01 works correctly)

Impact:

• Breaks scheduling accuracy
• Makes the feature unreliable for time-sensitive communication

Issue 2: Read Receipt UI Corruption

Description:
After enabling the read receipt feature, parts of the UI become visually corrupted.

Observed Behavior:

• Text rendering appears garbled or misaligned
• Layout is partially broken
• Interface readability is affected

Impact:

• Degrades user experience
• Makes message status unclear

Environment

• Platform: iOS
• iOS version: 18.7.8
• Telegram version: Latest (App Store)

---

Expected Behavior

• Scheduled messages should remain on the selected date and time
• UI should render correctly after enabling read receipts

---

Actual Behavior

• Scheduled messages shift to the next day when set at exact hour (xx:00)
• UI becomes corrupted after enabling read receipts
