region CLI command output truncated to ~5-10 entries due to packet payload limit

[jirogit]

region command output is silently truncated when region names are long, because the reply is limited to a single LoRa packet payload.

In examples/simple_repeater/MyMesh.cpp:

uint8_t temp[166];
char *reply = (char *)&temp[5]; // reply = 161 bytes max

region_map.exportTo(reply, 160); // hard-coded 160 byte limit

With encryption overhead (CIPHER_MAC_SIZE=2 + CIPHER_BLOCK_SIZE=16), 161 bytes is already the physical maximum for a single packet. At 30-character names, only ~5 entries fit before truncation.

Proposed fix

Paging support for the region command:

region # page 1
region 2 # page 2
region 3 # page 3

Or a denser region list output using the existing exportNamesTo() which uses comma separators (1 byte) instead of newlines with indentation.

Fixed by PR #2236.
Implemented paged output for the region command:
region — first page (wildcard * + entries from index 0)
region N — entries from index N onward
Footer >N at end of each page indicates the next start index to use
No footer = last page
Tested with 32 entries × 29-character names on t1000-e.
