release v1.7.0: redesigned calendar with coloured system indicators

Use coloured system markers by default, preserve configured colours through settings migration, expose all template fields through native vault-path autocomplete, and remove the redundant Calendar heading.

 Configured systems live in `settings.dateSystems`, where array order is menu order. `DEFAULT_DATE_SYSTEM` (in `settings.ts`, typed `Omit<DateSystemSettings, 'id'>`) supplies the field defaults for a newly added row **and** the merge base for saved ones, so a system persisted before a field existed still loads with that field defined. `DEFAULT_SETTINGS.dateSystems` ships two:

+| `journal` | Journal | `periodic/journal` | `YYYY-MM-DD - [Journal]` | green (`#22c55e`) | one |

+| `meetings` | Meeting | `periodic/meetings` | `YYYY-MM-DD - {title}` | violet (`#a855f7`) | many |
+
+The default calendar mode is `systems`, while `any` preserves the older one-neutral-dot behaviour. Template file fields in both Periodic Notes and Date systems use a native `datalist` populated from every Markdown path in the vault (without the optional `.md` extension), so templates stored outside a conventional `Templates/` folder remain discoverable.

+**`getDateSystemIndicators(dates)`** — returns one `{ id, name, color }` marker per configured system with one or more notes on a requested day. The calendar calls it once for the visible month only in `indicatorMode: 'systems'`.

It does not run on ordinary markdown edits: content edits cannot change a filename-derived indicator.

 **`dateSystems()`** — every day-scoped system in menu order: the daily periodic note, synthesized into a `DateSystemSettings` from `settings.daily`, followed by `settings.dateSystems`. The daily note is therefore not a special case in any consumer.
 
 **`findDateSystemNotes(date)`** — **one** vault scan per call, not one per system. It formats each usable system's `before`/`after` affixes for `date` once, then walks the markdown file list a single time, bucketing each file into the system that claims it (`isInFolder` + `matchesSystemName`). Systems whose formats have no date token are omitted rather than offering an unsafe create action. It returns the remaining `DateSystemNotes` in `dateSystems()` order, each bucket sorted by basename.

 `Name format` uses moment.js tokens. Bracket-escape literal text: `YYYY-MM-DD - [Journal]`. Add `{title}` when a date can have multiple notes; it is replaced with the title requested when creating a note. Without `{title}`, the system has exactly one note per date.

+- **Colour by note system** — the default; one compact coloured dot per configured date system that has a note on that day. Hover a dot to identify its system.
+- **Single dot** — a neutral marker for any note whose filename is exactly the date.
+
+Daily uses the Calendar tab’s colour picker. Journal, Meeting, and every custom system have their own **Indicator colour** picker under **Date systems**. The defaults are blue for Daily, green for Journal, and violet for Meeting.

 ### Templater folder templates
 
 If a date system uses a Templater folder mapping, leave its Waypoint **Template file** field blank. Waypoint then creates a safe fallback note while Templater owns prompts, scripts, cursors, and rendered content.
