Show uptime as readable text

[bharvey88]

Version: 26.9.29.1

What does this implement/fix?

Replaces the numeric Uptime sensor with ESPHome's built-in uptime text sensor, so Home Assistant shows uptime as 3d 4h 12m instead of a raw count of seconds. Thanks to @kernelpanic85 for the idea in ApolloAutomation/R_PRO-1#72.

• Uptime is now a text entity. Its history graph and long-term statistics stop, and any automation or template that treats uptime as a number needs updating.
• Home Assistant sees it as a new entity. The old numeric Uptime entity will show as unavailable and can be deleted.
• The ID stays sys_uptime, so component.update: sys_uptime in the report scripts still works.
• At the 60s update interval ESPHome leaves seconds off, so uptime under a minute reads 0m. Battery devices that sleep right after reporting will usually show 0m.

Walkthrough

The ESPHome firmware version changes from 26.8.27.1 to 26.9.29.1. The uptime entry moves from sensor to text_sensor, retains its 60-second update interval and sys_uptime ID, and adds a space separator.

A space now marks the time,
The firmware number hops ahead,
The sensor finds a text home,
All set beneath the moon.}
