Thomas Vincent 57b8088e13 docs: comprehensive validation audit, Spine poller overhaul, and technical refactor (#229)
* docs: comprehensive audit, Spine poller overhaul, and technical refactor

- Overhaul Spine documentation (Spine.md) with complete end-to-end guide: architecture, prerequisites for modern distros (EL8/9 CRB, Ubuntu 22/24, Debian 11/12, FreeBSD), SUID root permissions, secure spine.conf setup (0640), Web UI configuration (Paths, Poller type, Data Collectors tuning), MySQL max_connections sizing, and troubleshooting.
- Fix broken links and anchors (Hardening, SNMP data queries, Hook API references).
- Fix broken image reference in Sites.md (add-site.JPG -> add-site.png).
- Fix syntax errors in documentation PHP code blocks, including invalid parenthesization, missing SQL execute quotes, and malformed comments in FAQ.
- Fix DevOps installation commands: use config.php.dist, correct systemctl service names for MySQL/MariaDB/PHP-FPM, remove nonexistent php-json, add missing composer install, and correct Debian/Ubuntu systemd environment path.
- Correct grammatical errors, repeated words, and typos across all markdown documents.
- Remove obsolete unreferenced duplicate installation guides.

* docs: correct reviewed examples and guidance

* docs: correct guidance that disagrees with the Cacti source

Verified each claim against include/global_arrays.php, lib/auth.php,
lib/functions.php, host_templates.php and the Spine config parser. The
notable ones: api_plugin_safe_exec() does not exist on either branch,
Spine reads DB_Pass rather than DB_Password, and the CDEF special data
source table was missing five entries and renamed four others.

* docs: wrap Spine prose and fence the connection sizing formula

The formula's bare asterisks rendered as emphasis, dropping the multiplication signs.

GPRINT Presets

GPRINT Presets are an object in Cacti used for formatting Legend output on RRDtool Graphs. These GPRINT Presets closely follow printf(), sprintf() ANSI syntax. They are simple to create and edit. You can find the format strings on the RRDtool Website.

The stock GPRINT Presets are generally sufficient for most Graph Templates, but they can easily be extended, and are a part of the Graph Template Export XML file. So, they are portable once created.

In the image below, you can see the default GPRINT Presets and the actions that can be taken on them. Keep in mind that once a GPRINT Preset is being used by a Graph or a Graph Template, it cannot be removed.
