feat: add configurable tooltip position and offsets

[Xerrion]

What

Adds configurable positioning for the PhDamage companion tooltip frame.

Why

The tooltip was hardcoded to anchor below GameTooltip (SetPoint("TOPLEFT", GameTooltip, "BOTTOMLEFT", 0, -4)), causing overlap when the default game tooltip is positioned at the bottom-right of the screen.

Changes

• Core/Init.lua — Added tooltip defaults (position, offsetX, offsetY) to DB defaults; calls ns.Tooltip.ApplySettings() in OnInitialize
• Core/Options.lua — Added Tooltip section to options panel: position dropdown (BOTTOM/TOP/LEFT/RIGHT) and offset sliders (±200px) with per-arg DB key handlers
• Presentation/Tooltip.lua — Replaced hardcoded SetPoint with POSITION_MAP-driven anchoring via ApplySettings(); reads from AceDB profile

Review

Both reviewer passes completed clean. Defaults preserve old behavior.

Closes #53

Release Notes

• New Features
  • Tooltip positioning is now configurable. Users can customize tooltip placement location and adjust horizontal and vertical offsets through dedicated settings controls to suit their preferences.

📝 Walkthrough

Walkthrough

The PR adds configurable tooltip positioning to resolve tooltip overlap issues. A new tooltip settings table in SavedVariables schema captures position type and X/Y offsets. A new ApplySettings() function reads these settings, maps position names to anchor point pairs, and repositions the companion frame. UI controls let users adjust positioning and reset to defaults. Initialization calls ApplySettings() at startup and after hooks are installed.

Changes

Tooltip Positioning Configuration

Layer / File(s)	Summary
Tooltip positioning schema and defaults Core/Init.lua	SavedVariables schema extended with tooltip table containing default position, offsetX, and offsetY values.
Tooltip positioning implementation Presentation/Tooltip.lua	Local variables store resolved anchor points and offsets. ApplySettings() function reads config, maps position names via POSITION_MAP to anchor pairs, computes offsets, and repositions companion frame. Frame layout re-anchoring uses resolved state instead of hardcoded SetPoint("TOPLEFT", GameTooltip, "BOTTOMLEFT", 0, -4).
Tooltip positioning options UI Core/Options.lua	AceConfig options group added with TOOLTIP_POSITIONS mapping, GetTooltip() and ApplyTooltip() helpers, position dropdown select, horizontal and vertical offset range sliders, and reset action that copies defaults and reapplies positioning.
Initialization and lifecycle wiring Core/Init.lua, Presentation/Tooltip.lua	PhDamage:OnInitialize() calls ns.Tooltip.ApplySettings() to apply saved positioning at startup. Tooltip deferred initialization calls ApplySettings() after hooks are installed.
